This channel is about new generation of mechanical puzzles, including gravity puzzles, puzzles from my collection, and more. Many of my puzzles have been presented at International Toy Fairs and have impressed many people. The gravity puzzles are based on vatious mathematical concepts, e,g, some allow different shapes to be used (not necessarily pyramids) with other non-gravity mechanisms. Nowadays, I have started Greece's only Puzzle Museum and I organise Puzzle Festivals to enhance educactional efficiency and to inspire young and adults by exposing them to many of the world's most impressive puzzle mechanisms.
