And it does just that. When you sign in, a big old window opens up with a slew of simple.apps and a simulated second desktop. It's all Flash, and it works pretty well on my Mac.
Newer Macs running OS X will still open older applications in the old OS 9, also in a new window, and I love doing this because it gives me the feeling of a machine within the machine. Desktoptwo.com adds another funny layer to this, piping the machine within the machine through a browser.
Okay, off to try out the simple.apps and see if they're any good.
