JaysOS: “…is a ‘toy OS’ that runs on the Gameboy Advance. It provides preemptive threads, semaphores, condition variables, and message queues… There is also a “shell” app, which works over a serial connection (e.g. MBV2 cable), and allows you to control what is going on using simple commands.” Lots of free time + smarts = cool and (un)useful stuff.
The other night I watched a television program where a monkey chewed a whole banana, spit it out on a piece of wheat bread, spread the banana with its tongue, placed a second piece of wheat bread on top, and then ate the whole thing like a sandwich. I love TV.
