Busy weekend but I was able to get my app out. My little brother was all like you should make textsfromlastnight for funny YouTube comments.... Probably wont win any awards, but I had a lot of fun! :) Its cool to see a lot of other people went solo too and came up with some cool stuff!

Man! I'm noticing so many bugs and stuff. Not being able to change, fix, or edit this until next week is going to drive me crazy.

My coworker built http://upti.lt/ - a trump card game. Pretty fun and very polished for a 48hr project.

Imagine that now responding to your customers' appeals is a great fun. You get no spam or junk mail anymore, there are neither dispatching questions to one of your colleagues nor assigning of your own ideas to someone else. How about making a computer classify appeals and assign them to the right person? http://ideahq.r12.railsrumble.com/

Our team had a ton of fun. Hadn't participated since the very first rumble years ago, which we won in the design category.

Since we spend our days working on serious stuff, for this rumble we decided to do something funny (whether this is funny is actually up for discussion). http://getreadytojoust.com is what we built.

Our team build Jingle Boogie. It is app for making short jingles from youtube or vimeo movies.

I've created app for sharing code scraps (snippets) across group/organization. Made just be me, aims to solve real problem, that we have at my company. http://scrapsapp.com/

Our team built Github Death Star to put some order in your hundreds starred repositories.

We also love octocats!

We built a Star Trek game. Fun to play with a friend http://the-glimmer-twins.r12.railsrumble.com/

Thanks to the organizers and sponsors, it was a lot of fun!

Glad to hear that! It's not easy, but it was definitely worth it :)

Thanks guys! Looking forward to participating again next year!
