This is a infinite mirror design.

Is made for 10x10cm plastic mirrors. I bought them on eBay.
A plastic or a glass is needed for reflection and loop effect. I used policarbonate, works fine.
Between the 2 layers I placed a 12V led strip.

Materials needed:
-10x10cm mirror.
-10x10 cm transparent glass or plastic.
-Led strip.
-Glue.

Tips:
Use glue to paste the led strip and to fix the top of the design.

I will try to make a second and improved version soon.
