So, we challenge everyone and especially those who made submissions to the erco figure eight challenge to make a photo or video of your favorite artistic robot drawing a spiral pattern. Per Nikos' intent and erco's question - this can be any sort of spiral - see original thread.
Post away! When I can, I will post a video of the S2 completing the challenge. Till then, here are my still photos! Also attached is Spin for the S2.
