A little late to this one, but thought I'd contribute my efforts!
Firstly, these are all so great. I think the 64Door and the Tools one are my faves. You've rendered those latches on the toolbox perfectly!
So I totally got inspired by these to make some of my own for 'Old Blue'. Well I needed a couple of icons anyway and then I remembered something about IconMaster and AmigaLove. Of course I blindly downloaded the wrong Aminet one first, when I should have come straight to the source!
Here's a start. The sizes are all over the place and the light sources are totally inconsistent. I figure if I made 10 or so more of these I'd start to get a harmonious look. I do like the tiny A1000 - that one might be a keeper.
I think the fun part is coming up with the two step 'animation' (for normal and select state) - you're essentially telling these little two frame stories while trying to convey the utility of the item.
