What does a child of the '80s who really wants a dog or cat as a pet without ever having to clean up after them do? Obviously they hack apart a bunch of foam floor mats and turn them into a life-size replica of Ravage from the Transformers. This version doesn't transform into a cassette tape, but it still looks amazing.
If you want to try building one of your own, head on over to the Seibertron forums where Jamie Young of FoamTastic Props fame has posted a huge collection of photos of this build in progress. You'll still need some decent skills with a hobby knife and glue gun, but the results are totally worth a living room covered in bits of foam. [Seibertron via Geyser of Awesome]
