Strandbeest leg System
I am not in any way involved in the idea, design, making or marketing of the "Strandbeest" (Dutch for "beach beast"), nor am I in any way affiliated with the person(s), company or organisation behind the Strandbeest, but I, as a spectator, find this art work fascinating. I made an interactive animation of the "core" of a Strandbeest; the leg system.
Figure 1 is an interactive animation of the bar linkage that the "leg system" is. Drag the red dot over the grey circle's circumference to make the linkage move.
