I reviewed videos and photos to understand what this would actually look like. Then I 3D modelled the belly of a rowing shell and the blades of some oars and 3D printed them. I Laser cut (or rather engraved) the shapes of the waves around the shell and the oars out of a sheet of translucent acrylic. I glued the 3d printed parts on the bottom of the acrylic sheet. Then I built the body of the lamp, and installed RGB LEDs against a randomly reflective background out of crushed up aluminum foil. I then programmed an Arduino to create the appearance of the change of colour and flickering under water in the LEDs.
