Lens Head Robots

Here are the Lens Head Robots designed by Makino Shunichi.His website is http://www7a.biglobe.ne.jp/~sf-papercraft/.
There are four robots in the original collection. Unfortunately, there are only two left.

These were fun (but a bit challenging at first) to build. They do have a great deal of greebling potential (if you wish to try your hand at such).
