Talos02 by dryvval. The legs on this are really
slick. I'm not sure how big it might be though.
Bug Invasion by AC Pin. These look to be about minifig size -- since
they use some minifig parts -- which would put them at 4P scale.
Prototype by Dead Frog Inc. This one looks very fiddly. There
are some interesting parts choices and techniques though.
Doodle by Drew. It could be a little fragile but, it has a great look about it.
