Toroflux
A mesmerizing kinetic sculpture and an interactive "flow toy" that's like a 4th dimensional "slinky". It folds down in a spiral direction to form a ring of rings and with a subtle movement, it pops open into a full torus of interconnected rings, surprising everyone. Comes with a mini-biner, so you can easily clip it to your bag or belt loop and bring it everywhere to share and spread the fun :)
