| The projector is shown in the left picture and the projection it makes on the ceiling is
shown in the right picture. |
| This projector works on the same basis as a lava lamp. A disc contains oil suspended in
liquid of two different colours in two different layers. The disc slowly spins and as the
oil heats it forms interesting patterns projected on the ceiling.
|
| The shapes are very soothing and keep me transfixed for hours. |
