One in particular is a rotating Earth.

An easier, and maybe almost as rewarding, idea is to get a long lifting stick/pole to lift uglier thrift store battery-operated tape players into places that are hard to reach. Looped tapes would be playing in them, battery powered.

It would be interesting to have all 128 tracks of the MIDI album playing at 128 different locations in town as the show of the album.

I don't have any tape players I completely wouldn't mind losing in the name of creating a dream world for one night in one place, but maybe I'll take the one I like least.
