This is beyond brilliant. Not because it's More Hard Fun From The Maker Of QWOP, but because it's actually easier than QWOP, and it tickles exactly the same part of my brain that bouldering itself tickled, and it makes brilliant use of finger-gymnastics and the keyboard, and it's marvellous, really. I just want to go home and play it all night.

"Deep craft is more than knowledge. It is a set of knowings. Knowing what is likely to work and what not to work. Knowing what methods to use, what principles are likely to succeed, what parameter values to use in a given technique. Knowing whom to talk to down the corridor to get things working, how to fix things that go wrong, what to ignore, what theories to look to. This sort of craft-knowing takes science for granted and mere knowledge for granted. And it derives collectively from a shared culture of beliefs, an unspoken culture of common experience." Craft / scenius / place / knowledge. The W Brian Arthur sounds great, and Matt's point – that building strength in a sector is building culture, and that requires investment in something that won't see immediate returns (rather than "five-year plans" and "strategies") is acute. Very good stuff.
