You can see it here. It works just fine in Chrome/Firefox, but IE9 doesn't do rounded corners on the fieldset elements, and also doesn't do the background colouring. No idea why, but if someone wants to illuminate me then that would be awesome.
Also, if it looks appallingly bad in your browser then send an email to email@example.com and I'll see what I can do. I'm not promising anything though - supporting more than FF/Chrome (and making sure it's usable in IE9) is enough of a workload for a hobby app :->
