"The SSS-12 is probably the best hardwood sequencer to ever be put on water. An incredible machine, It stores and plays the last 12 hours of river samples. Custom circuits convert the saltiness of each sample into pitch, the more salt the higher the pitch, giving a sonic impression of the tidal cycle. With its wooden conveyor belt the SSS-12 automatically updates every hour so you always get to hear the last 12 hours of tidal activity."

Wonderful.

"Passing the salt will never be the same. We all knew it was inevitable. Passing the salt by hand just isn’t efficient enough in a world of bullet trains and pizza delivery and broadband. Luckily the condiments have come to life! They will waddle wherever you tell them to, so the next time someone wants the pepper, wind up the key, and pepper they shall have! Mercilessly marching towards them like the terminator, more of a threat to dull tastes than the human race." Not sure they're £20-good, but I do like this condiment set made of small robots.

"Here’s a complication of some common and useful time & date calculations and equations. Some, though very simple, are often misunderstood, leading to inefficient or incorrect implementations. There are many ways to solve such problems. I’ll present my favorites." These are, indeed, useful, and I've been using a few of them recently.
