One of the two best christmas presents I ever got, was the year I got Ultramagnus and Megatron. I thought about making one of them for the challenge, and when I was google searching for images, I couldnt believe how simple they were. I must have got mine when I was about 8 or 9, and Id always remembered them being so intricate and impressive....was pretty shocked when I saw the pictures of them the other day. I decided I didnt want to make one unless I actually had one in front of me, rather than working off of images. Be cool to see Bumblebee. Will still be pretty intricate for modelling, and with bumblebee, he's got a good mix of curves and straight lines.
