My third iteration of the car/robot transformer finally achieved a decent-looking car form. I also bought some more black parts, because it turns out you need a lot of those small 1x1x0.33 bricks. This is easily the most complex of my transformers so far, with still reliable and relatively sturdy joints/etc. The robot form is also OK, although not as posable as my ver. 2 robot.

I’m starting to feel like I should move away from the repeating yellow/black theme, and looking into widening my parts collection now that I have an idea what parts I need for a car/robot transformer.
