Well with all the recent intrest in Transformers I rember this site being posted a while back,
http://www.cosmicrust.com/downloads/paperformers/
They have some simple paper Transformers that actually transform. The site has the files but no pics of any completed models so last night I decided to try building one and succeded
I chose Sunstreaker as my 1st paperformer. I noticed a few mistakes in the parts though. 1st the tires were mising a segment of tread, easily corrected with a piece of card. And the big boo boo was in the rear fenders. They were too short and one of the tail lights was upsidedown. I added to the fenders to correct the size but couldn't really do anything with the tail light. I'll have to study the parts sheets of any furture builds and correct any mistakes before the build
Alright enough gabbin, time to show the model 
Here's the car mode,
