a concept
Who among us wouldn't like a simple, cheap mechanical fish? Solar powered, two brightly-coloured triangles connected together like so: <<
The connector is a spring that flexes when energized. Trickle charge is collected from a tiny solar cell, and released when there is enough power to flex the spring.
The fish should have neutral bouancy and swim in circles. You really want a collection of five or so, all swimming in the same direction.
