This is our (Catalyst Studios) latest project, a live pizza giveaway. We think it'll be funny and entertaining, so check it out! You may get some free pizza out of it. There are slices given away via a form, and bundles of slices given away for contest submissions.

For the tech curious, the backend is C# .NET and MongoDB for most of the persistence.
