For an idea so simple - taking some wooden poles and strapping them to your legs - stilts haven’t been improved upon much in the past few centuries.
What if you made your stilts out of (playable) organ pipes? Or maybe make the length auto-adjusting so you can step into them and raise yourself up comfortably? There’s also a lot of artistic room, here: persistence of vision using LEDs or kinetic sculpture attachments are particular favorites of ours.
The sky’s the limit here, or at least as high as your stilts can reach!
