I learned about a new mono font called departure mono (git) that looks really neat.
This is what it looks like:
It's got this pixel style vibe to it, and it is perfectly suitable as a mono-font.
It could work well in some video games or websites that have a retro element to them but I think you could even set it up to be the font you use inside of your terminal or IDE.
It's not going to be for every project out there, but a good font can really make a demo great. Especially when you have something for developers.
