We combed through the pictures that people uploaded from Nationals and tried to pick out all of the top 10 placing devices. Eyeball and starpug helped identify some of the ones on the image gallery too, if you check out some of the image comments over there.
The result is this wiki page: The Best of 2009 Wiki
We obviously don't have pictures of every top ten device, but we have at least one of the top 10 for every event except Elevated Bridge C. Most of the events have two or three entries right now.
Check out the pictures and add comments or questions about the designs!
If you have more pictures of one of the devices or pictures of other nationals top 10 devices, you can upload them yourself on the wiki, the image gallery, or shoot me a PM.
Should we try to do this next year?
