Every time I see these things, I wish Sixel graphics[0] were better supported, or else some more modern alternative.

Being able to use GNUPlot with Sixel output or tools like lsix[1] is really cool! I think if support / libraries / knowledge about Sixels was more widespread, we would see some really nifty terminal applications cropping up.
