constructive logic

Tom Murphy (suckerpinch) presents a deliberately trollish computer architecture built on IEEE-754 floating point, using NaN and infinity to define logic gates. He builds working hardware around the idea.

The Thought Emporium grows living rat neurons on an electrode array and tries to train them to play Doom. It is part of a series on biological computing.

Matthias Wandel shows his wooden machine that adds binary numbers using marbles. It demonstrates computation with purely mechanical logic.

An old lab video of a decerebrate cat walking on a treadmill and shifting between gait patterns as the speed changes. It is used to illustrate that much locomotion control comes from the spinal cord and body mechanics rather than the brain.
