Yossi Starz has released his LUA Ys-OS version 1.0. Ys-OS is the first multi-processing shell written in Lua scripting language. Basically, that means you can run multiple programs at the same time. I have to say, this one is really cool to see. I opened an explorer window, the star field demo and a png image in the mean time. The star field was running smoothly as long as it's focused on. Here is the description of this version:
