I'm going to make a massive puzzle with these. A machine enchanted to crate with randomized tetriminoes made up of 5' blocks in a machine that's exactly five foot thick fifty feet wide and 100 feet tall. it will also have a control that uses telekinesis to manuever the blocks in 90 degree angles, left and right, Really fast down or slower up. If they make a line, then a disintigration spell destroys it and the blocks all move down to fill the cleared line.
If a block reaches the top, epic brickfall in the whole room! Mwahahaha.
