I love terminals, but I have to say, I kind of hate this sort of thing? Where you need at least 256 colors, GPU acceleration, and 240 columns x 80 lines? At that point it's just a curiosity, anywhere you could do that in a terminal you could do it easier and better in a graphical window. I want my terminal apps to actually still work in an 80x24 monochrome VT220 at 19200 baud. I want them to use termcap instead of hardcoding xterm's extensions to ANSI.
