Different sort of potential communication medium

[dsteve54]

Kinetic sculpture. I just thought it would be of general interest as a different medium.

Don't know how I missed this one when it came out, but I've seen it now.

I loved the cool sand walkers. I'm rather less pleased that it turns out to be an ad for BMW.

I'm wondering, too, just what this is meant to "communicate." What does it mean?

Hey, someone has to pay for art!

I just wished he could have made a wind-powered walker that sifted the sand to remove the trash left by beachgoers, but then, that's just the practical side of me taking pot-shots at the artistic side.

Somebody ought to coin a specific word for these contraptions. "Kinetic sculpture" and "sand walker" aren't quite descriptive enough. Any suggestions?
