When having a romantic streak, normal heart shapes are not enough for me. They have to be special. That’s why I wrote an ASCII art generator.
Be warned: It works in Firefox 3.5, and I suspect nowhere else. I do not care enough, but if you want to improve upon things, I put the code on github.
Also, it’s really slow, but that’s the prize to pay for doing graphics in Javascript. ;)
