the idea: a DIY Rolling Coaster Rollercoaster

the ideator: Viktor Genel

I met Viktor a few months ago now and he gave me this absolutely beautiful puzzle box he made, which now has a proud place on my wall-to-wall bookshelf.  Then today I saw a great video he put together while he was on vacation.  As a puzzle-maker, it seems that Viktor can’t go anywhere without making something, a sentiment I completely agree with.
