Hackathon Be Gone
In Austin, we started running an event called "Finish Up Weekend" or FU Weekend - http://fuweekend.com/ ;)We have some simple rules:*  you can't start anything new;*  you have to celebrate something being done - usually with a round of applause;*  there are no prizes - only the satisfaction of being done.While there is plenty of coding, we've had designers finish their portfolios, screenwriters finish pilots, an artist finish his display, and even saw a sewing project completed.And to top it off, we charge a nominal $20 for the weekend - with 4 meals, a great deal - and sell out every time.We're putting together a howto doc to franchise the idea.. just need to finish it. ;)
