Believe it or not, artist and wood-savant Paul Grundbacher doesn’t draw up a rough schematic or do any kind of planning before he starts building his amazing marble machines.

That approach also means he spends a lot of time re-building mechanisms when they don’t quite work, but the end results don’t disappoint.
