Ole Kirk Christensen’s Wooden Blocks

Origin
Ole Kirk Christiansen was the creator of the LEGO building blocks toy. He created them originally from wood as a toy for his children and later moved on to making them out of plastic.

Effects
The blocks will arrange themselves into a structure needed by the user (steps, ladder, bridge, etc.) To be dismantled, they either need to be taken apart piece-by-piece or the structure smashed into.
