A skate park, that is able to be ridden normally but if a RF sticky ticket is bought then a whole new dimension is opened up.

The surface of the park is a heavy flexible material that hides pneumatic deformation rams. Position sensors, using the RF sticker, will time humps and bumps to slow, jump or accelerate the skater.

[Aside] I was trying to mentalise how a photon leaps an electron. Does photon ramp, bounce or head on collide with the electron? It made me wonder whether the connecting photon was just the camels straw. Is there an experiment that is a true isolation the single photon, single electron interaction?
