Do any of the KRE-O Transformers sets actually transform? KRE-O, a LEGO-compatible brick toy, has several officially licensed Transformers models. I have two of the smaller ones and they do not actually "transform" - you take them apart and put them back together in a different form.

Do any of the sets use model functions to provide transformation, or are they all simply different models using the same bricks?
There's an almost 20 minute video about the kre-o Optimus Prime at youtube where pretty much everything is shown in detail - except the transformation itself. I'm really sure that if this was possible without disassembling and building it from scratch then it would be shown here, so the answer seems to be: no.
