Nice interview and profile; when I read it, I remembered how much I enjoyed _Grafts_.

Some properly gnarly games maths, laid out. I understood some of it? But always nice to see what goes into things, even when you don't enjoy them, especially at that technical-art conjunction.

Really nice tutorial on 2D visibility polygons – a series of interactive demos that illustrates a point very well.

"Topics like linear algebra, topology, graph theory, and machine learning are becoming vital prerequisites both to doing daily work in these fields and, more importantly, to inventing, popularizing, and teaching the new creative tools that are rapidly arising. Without them, artists are forced to wait for others to digest this new knowledge before they can work with it. Their creative options shrink to those parts of this research selected by Adobe for inclusion in prepackaged tools. Instead of the themes and concerns of creative work driving the selection of tools from a growing technical cornucopia, artists find themselves turned into passive users of tools that are already curated, contextualized, and circumscribed by others.

So, I want to do something about this. I want to figure out a way to teach myself and others these more advanced mathematical and computational concepts with a specific eye towards applying them in creative technology."

This is going to be very good. (I'd quote the whole post if I could, but this leapt out at me hardest.) And: on the day Greg's book arrived.

"I would call him the greatest puzzle designer of all time, but that implies that there are lots of people who do what he does and he’s better than them, and that’s not quite right. What I mean is to say is that Raymond Smullyan is the Marcel Duchamp of puzzles, he’s the Brian Eno of puzzles. His work is singular, transformative, genre-defining, in a class by itself."

""The Iraq War: A Historiography of Wikipedia Changelogs" is a twelve-volume set of all changes to the Wikipedia article on the Iraq War." James is brilliant, but I knew that already. This is quite a thing.

"You never see anyone using a slide rule in a film. Matinee idol scientists always work out algorithms unaided in their brilliant minds, or scrawl them manically in chalk on giant blackboards. By the same token that unfairly condemns people with colour-coded ring binders as the owners of overly tidy minds, slide rules are supposed to belong only to the pedantic foot soldiers of science, the plodders who have to show us their workings out. But slide rules are lovely things: pleasingly solid, elegantly mysterious in their markings, the perfect marriage of form and function." Joe Moran on slide rules and scientists.

Dan on Torchlight and Borderlands: "…they both tickle the same fetishistic urge to collect, developing bigger and better attacks to have much the same effect on bigger and better monsters as your last set of attacks had on the last set of monsters. Every single decent-sized beastie in each one drops loot when they die. Throw in a two-car carport and this is a precise map of adult life, except fun." I really need to do my goty.cx write-up quite soon.

"Use [ffffl*ckr] to find the photography you like using the simple idea that people whose work you like, probably like stuff you'll like. You start with a set of pictures – if you authenticate, it'll use 20 of your last 100 favorites – otherwise it'll start with somebody's favorites. Click any picture to load more. Don't like what that person likes? Scroll back and click a different picture you like. It's that simple."

Fascinating: GPS satellites are both high enough, and travelling fast enough, that you need to correct for relativistic effects in order for them to be effective.

"To whomever it may concern, In response to the unfortunate circumstances, some wives of Rockstar San Diego employees have collected themselves to assert their concerns and announce a necessary rejoinder, in the form of an immediate action to ameliorate conditions of employees." Jesus. Once again: the games industry treats its staff appallingly. As the first commenter says: "It's a video game people. Find a way to make one without imposing unethical, illegal, and debilitating working conditions."

"One of the world's finest compact fountain pens, the excellent Tasche measures just 98mm closed, but opened up becomes a full-size pen at 145mm long. The secret is the extra-long cap, which almost entirely swallows the rest of the pen when closed, but posts firmly onto the top of the pen to create the full length." Possibly another distraction before I succumb to buying a Vanishing Point

"It is not hard to cut a bagel into two equal halves which are linked like two links of a chain." And now you know how.

"The game is very impressive, and gives some great experiences. For example, a friend at work solves most problems with a jetpack and a lasso, instead of a grappling gun. In his heart he's a cowboy, and in mine I'm Batman." A comment on Brandon's year-end post about the uncanny valley of Scribblenauts; this line really, really stood out for me.

"Sides chosen as Demo-Soldier tension mounts". I love Valve. I love them so very much. I reckon TF2 is the unsung hero of their games, frankly – and their continued dedication to it is just marvellous.

"But 2009 was about a lot more than that handful that we knew would top their respective Metacritic charts (and retail sales lists) six to nine months before their release date, and… this list for Boing Boing will instead focus on the games that left their own strong mark on the year, just, sadly, a mark that in most cases went mostly overlooked." Brandon kicks off his end-of-year list. It is good!

"…even if they make the rules explicit, it’s not going to help the “power-leveling problem” which is ostensibly the reason for all of this grief. Unless they remove all difficulty options from the system, there will always be easier and harder ways to level. And remember what I said above: users tend to prefer easier content with better rewards. This isn’t limited to user-created content — it’s true for designer-made content, also. But designer-made quests don’t get graded by the players. Player-voted content like this will always gravitate towards easy. And pick-up groups will always be picking the most rewarding content with the least annoyance. And the game devs will keep being unhappy about it." Smart analysis of the problems with City of Heroes' user-generated missions.

"Games don't separate learning from assessment. They don't say "Learn some stuff, and then later we'll take a test." They're giving you feedback all the time about the learning curve that you're on. So, they're not the only solution to this problem by any means, but they're a part of the solution of getting kids in school to learn not just knowledge as facts, but knowledge as something you produce; and in the modern world you produce it collaboratively." Jim Gee is a smart guy. I need to read more on him.

"I suggested that, when it comes to the design of embodied interactive stuff, we are struggling with the same issues as game designers. We’re both positioning ourselves (in the words of Eric Zimmerman) as meta-creators of meaning; as designers of spaces in which people discover new things about themselves, the world around them and the people in it."

"Statisticians’ sex appeal has little to do with their lascivious leanings … and more with the scarcity of their skills. I believe that the folks to whom Hal Varian is referring are not statisticians in the narrow sense, but rather people who possess skills in three key, yet independent areas: statistics, data munging, and data visualization. (In parentheses next to each, I’ve put the salient character trait needed to acquire it)."

Ron Gilbert plays The Secret Of Monkey Island again, and takes notes. Nicely measured – neither grumpy nor jubilant, it reads like an interesting director's commentary. Good stuff.

"This week I've killed Steven Spielberg three dozen times. I'm feeling better about the whole thing now, so I'm not going to vent any more steam about his increasingly asinine – and frankly pretty arrogant – repetition of the 'games won't be important until they can make you cry, which up until now they haven't been able to, but don't worry I've come to fix things' line." Which, you know, is good, because it means Margaret can talk about the joy of cubes instead. Or Cube, to give him his proper name. A wonderful One More Go, this week.

Ooh, this looks like a very interesting write-up of a thoughtful SXSW session. Marked as something I need to follow up on.

"You don’t need to be able to lose for a game to be enjoyable or challenging. You just need to be able to fail." Some good notes on the purpose of failure in games, and how to sensibly work failure as a mechanic into games without irritating players.

The Klein Four are "the premiere a capella group of the world of higher mathematics". Judging from this video: yes, so they are.
