This is amazing!
Reminds when I was doing my own bitmap fonts on ZX Spectrum and Amiga. They were probably very ugly by today's standards but they were mine :) I guess I'll create one for my terminal, it probably won't be used there for too long but it would remind me of times when I was more in control of my machine.
One does not need a WWW-based editor to make that kind of font, if you're going to give it a go. A text editor and Viznut's perl scripts yields BDF files quite straightforwardly.
