As a matter of fact, there's already one out there!

I've been contributing some code. It's called glyphdrawing.club and is a lot of fun. No colors yet, but they are coming next.

Check it out:

I also recommend checking out glyphdrawing.club for a contemporary web-based editor using inventive unscii fonts. It features an original font and some contributor-submitted ones! Really fun to play with.

I hate to be that guy, but if you care about descriptiveness the correct word would be "typeface", not "font".

I'd guess "font" is understood by more readers than "typeface", even if it is slightly incorrect.
