Ha ha ha! I really like how you designed a DDR arcade cabinet ergonomically for ponies! The cabinet itself looks fairly detailed! I see you've included the classic beatbox speakers and mobility rail. XD
This is beautiful work...and I giggle at the thought of a Ponyville DDR machine. It would probably be a crazy clockwork gizmo like an old player piano, with a hoof-crank to wind it up, bellows underneath the pressure plates to verify the steps, and rolls of punched paper with the tune and dance arrows loaded and rolling up the screen.
