Are you one of the nerds who write every second $3n73n(3 £1|{3 7h1$ (”sentence like this” for non-nerds)? Then you may be interested in this:

There is a Google frontpage completely written in Leetspeak, 1337, L33t or whatever you want to call it. So “Search” becomes “s3a|2ch”, “Advanced Search” will be “4DV4NC3D 534RC|-|” and so on.

If you are too lazy to write in such a weird way but still want to be “nerdish” then I would suggest one of these L33t converters:

Albinoblacksheep Leet Translator
Ultimate Leet Converter
1337-converter on devianART

Have fun being freaky
