Andy Wallace is only asking for $1,500 on Kickstarter to transform whiteboards and dry erase markers into fascinating, interactive gaming tools. When I was growing up, I found these marker boards to be a fascinating alternative to chalk boards. Likewise, I think Doodle Defense will be a fascinating alternative to traditional tower defense games.

Wallace explores in Doodle Defense drawing as a means for game interaction and play. Players draw mazes and color-specific towers on the whiteboard with regular dry erase markers to stop oncoming foes. Wallace makes it all happen with code written in openFrameworks on a Mac (a Windows version is coming) that handles the gameplay and the processing of players' drawings, a projector, and a Kinect that captures the board image.

Wallace last turned a few heads with Isabelle Poppy And Bling. Those unsure about this newer project can explore Doodle Defense's open sourced code before investing. With enough funding, Wallace says he will develop a more accessible iPad version, in addition to the Mac and PC experiences.
