Did some work sometime last year (or was it even 2013?) on the little wheels/big greenhouse thinigi, and I'm quite happy with the result so far. The 3d-model is still very rough, main proportions and surfaces are there, but it would need a lot of time in finishing and stuff like this which will probably never happen.
Working on projects I mainly thought about years ago needs a lot of motivation, which I dont have very often. So I did a few renderings a while ago to show the design updates.
Also, some package/comparison-screenshots for size-relations. Any comments?
