Autodesk is hosting the first AppHack at Autodesk University Las Vegas this year. There are great prizes for the top 13 AutoCAD compatible apps including a $5000 first prize.
To be considered, make a 5-min (or less) video that demonstrates the capabilities of the new app/plugin, the work needs to be submitted to this Buzzsaw repository, complete the Competition Participation Agreement, and if selected as a finalist – perform a live demo of the app at AU!
The contest has officially started and they are accepting submissions until November 14, 2012 @ 11:59 pm (PST). Please reference this site for more information.
