Swedish inventor Simone Giertz has revealed her latest creation: a website named after the way her last name is pronounced,’yetch’. Giertz’s roster of inventions includes things like a toothbrushing helmet and a gnarly vegetable chopping machine.

Yetch’s’incomplete white puzzle’ consists of 499 pieces out of a 500-piece puzzle. Since it is intentional, it will still cost you the full price of $ 38.

The calendar is available for $ 365 – a fitting price. It was part of her first Kickstarter Kickstarter campaign.
