Please review my webapp: Da Button Factory - create shiny buttons
palsecam: Thanks everyone for all of your comments!@brk: the method is pretty simple: the images are queried via Ajax to 
the server, which runs a Fast-CGI script, written in Perl, to generate 
the buttons. Javascript does the rest (visual effects, Ajax, CSS code generation...)@zepolen: thanks for reporting the problem in Opera, I'll investigate ASAP!@DXL: yes, color pickers and more powerful controllers in general (for
picking the orientation maybe, for example) are in the roadmap :-)@exalo: you are not the first one to tell me about a "randomize"
feature. I'll think of it seriously. Thanks. 
For the vertical
alignment: normally it should be centered, but the result of
"vertical-align: middle;" vary between browsers. I'll make it better
ASAP :-)
For the non-clickable title: actually it's currently just
a <h1> tag, but this will obviously change, you're right.
