You've seen John Edmark's trippy Fibonacci Zoetrope Sculptures, which bring animation to 3D-printed pieces via a turntable. For those of you who've read up on multicreative, multi-hyphenate Edmark's background, it'll come as no surprise that he's got more tricks up his sleeve than those. Check out other examples of his "playable art," this time made with a laser cutter:

That's the Helicone, which is now carried by the MoMA Store and the Guggenheim.

Maybe one day, someone will make a spiral staircase that unfurls on-site like Edmark's Nautilus Column:

Or with his Nested Gears, which are something like a static spirograph:

What would a wooden octopus' tentacles look like? Probably something like Edmark's Roll-Up Spiral:

His Folding Spiral has even more dimension(s), literally:

His Curling Spiral is guaranteed to freak out whatever household pets you have:

He also uses stop-motion to show you how some of his pieces are cut from single sheets of material, like his TransTower I:

Stop-motion is again used to show you how some of his pieces look in animation. In this video of his TransTower II, his hand turning the white knob up top has been edited out.

Lastly, his Incremental TransTower is powered by an internal mechanism designed and built by physicist Paul Stepahin.

Digg has turned a bunch of Edmark vids into beautiful GIFs (like the one up top) here.
