To further Rick's War Birds link, I found switches in the "miscellaneous" section of their site..

Use your brower's "Find on this page" function (under Edit if using IE) and type "switch"..IE should highlight all the different switches they have listed on the page.
Also, this project sounds interesting...please continue this thread or another with pics of your process/results. I know I'm interested for one!
