For a little change of pace, I'd be fun to focus on some non-game pixels in this edition. This week's theme and hint is "GUIs" — that is, Graphical User Interfaces (ala "Windows"). Name the GUI and the computer it ran on. The first block is to the right, the other two are below. As always, post your guesses in the comments section of this entry, and don't be bashful. Good luck!
The answers to the last challenge are after the break.
Last Challenge's Answers
I guess that my last challenge was too hard, because only Brian Beck really guessed anything. But he proved his NTP might (NTP for Name Those Pixels, of course) once again by getting the first two correct. No one touched the third block, though, which was a obscure game for the British dream machine, the Sinclair ZX Spectrum.
