I received my USB Missile Launchers from Woot the other day. I ziptied a webcam to the top of the launcher and then started looking at how to control it. Fortunately, I found some open source software called SharpLauncher. It's coded in C# using #SharpDevelop and opened without a problem in Visual Studio 2005. It didn't take long for me to hack the code to add xPL support to support panning, tilting and firing the missiles. It works great, but since I used the developmental version of code, there's lots of crashes using the GUI - but I don't need it using xPL.
