I've always been a big fan of ASCII based games. If I sit down to toy with a project, more often than not I'm doing something ASCII. I was never a great artist, but I loved Roguelikes (ADOM being my favorite) and had a mind to write a multi-player Roguelike back in the day.
Anyways, I just wanted to post about one of the coolest ASCII apps I've seen in a while. The name is Project Infiniverse. It procedurally generates universes with star maps and nebulae or planet surfaces with climate regions, vegetation, etc. It's pretty awesome to check out if you have the time and are on Windows.
The apps are programmed in my compiled language of choice, FreeBASIC. I'd love to be able to write algorithms like that. (There's the geek in me speaking. :D)
