I'm creator of Spark app (<a href="http://codefather.io/spark/" rel="nofollow">http://codefather.io/spark/</a>) - 37Signals Campfire chat client for Windows (8.1)<p>IMHO it's one of the best Campfire clients out there (iOS, and Android included). I've put a lot effort into creating it and really hope users will enjoy it as I do.<p>Feedback welcomed.

I don't use Campfire anymore but I do think that is a good looking chat client.<p>The promo site however needs a bit of work. There is just something about the combination of text, images, and spacing that makes it look unattractive.
