Linux! With a free program. That screen shot is was taken in real time and no editing. I think the name of the program is Berly. I am sure that is not the right name but reaaallly close... Oh, and the type of Linux is Ubuntu!
at the moment, I have Damn Small Linux running off of a flash drive within Windows... but it's sort-of a bare-minimum thing, so who knows what it'll run, and it's kinda slow... I'm going to try and boot it w/o windows at some point... but yeeeah... XD
