The guy who discovered how to turn ordinary stone into uraniumrock. Also does jigsaw puzzles, normally without using the reference photo, and mixing bags when there are multiple bags. Working his way up to bigger puzzles, but currently on a long detour into being a slow speed puzzler. Not very good at photography.

Current BIG puzzle: Heye 2x4000 Historia Comica Opus 1 and 2 (mixed)
