Thank you Oskar, for a lovely afternoon and the insight into your world.
Oskar van Deventer is a dutch puzzle maker. If that description makes you think about traditional dutch foot ware and wood, you couldn't be more wrong. It's 3D printers, pc's and unfathomably complicated mechanical problems. What we see are wildly colored toys, what we don't see is the "magic" inside. This magic is created by Oskar.
