Inspired in response to the Faux-parts/Anti-Kibble thread, I began wondering what was the most impressive, ingenious or most efficient designed transformation within a figure. I'm not really thinking about overall transformation, I'm sure that topic has been done to death, rather which steps in a figures transformation have really impressed you? I'll start with Alternity Megatron's arms. From a car door, seat and lower door frame you get an arm with fold out blade and fist along with samurai style layered shoulder guards and pointy shoulder pads with double articulation on these to move them away from the body. The first time I did this it was a revelation on how much articulation and manipulation could be coaxed from such compact area. I'm also very impressed with the upper body transformation I've seen in video's for MP Megatron. Very tidy! What has really grabbed you as great design within a transformation?
