Liquid Crystal Cafe – Names Hack

Last night I wrote a stupid userscript to exploit a stupid XSS vulnerability to add a stupid feature to a Web-based chat room I’m in.

Everybody else’s name is coloured in accordance with the theme they’re using. But mine… can be a rainbow, or an image, or something else entirely:

Animation showing Dan Q typing a chat message and selecting a 'style' from a dropdown, which is then applied to his name in the sent message, making it black-on-white rather (or rainbow-coloured, or the Dan Q SVG logo) rather than just plain coloured text.
