Working Principle:

We use laser engraving machine to carve patterns on the transparent acrylic board, and then install RGB LED light underneath. The light beam will emit from the carved area. We can also use highlighters to draw some wanted patterns on the acrylic board so as to realize the similar effect.

How to Make:

Step 1:
Firstly, we need to design an acrylic base. You can design it to any shape you like by yourself. We use laser engraving machine to cut two circles in same size from a transparent acrylic board. There are four small holes, which form a square within the circles. On one of the circles, we have made a hollow rectangle slot.
