Heh. I ran into this puzzle on the Test Realm today:
Which instantly reminded me of the floor puzzles in Dungeons and Dragons Online:
haha! You find these floor puzzles scattered throughout the dungeons of DDO all the time. Last night my static DDO group encountered a very complex one where if the puzzle connected with certain points on the ground, monsters would jump us. Good times!
Nice head nod to DDO, KingsIsle!
