Crosstips.org (and Krysstips.se)

Crosstips is a fun little side project that I initially coded over a weekend and has since been attending to to make sure it works and uses some innovative ideas.
One particular feature I'm pleased with his the handling of internationalization (aka. I18N) by using the domain and by using GEO IP.

It really works. You shouldn't cheat when solving crosswords but sometimes you just get totally stuck or it can be that you simply don't know the missing word. Crosstips, for me, isn't so much about actually solving crosswords but about a nice web application that actually does something useful.
