This is what the bottom looks like. I tried to make the resin as pigmented as possible to hide the electronics. When lit up and looked at in the dark, the electronics become somewhat visible as a silhouette.

Foto taken with surrounding lights on and the cube powered off. the Arduino is barely visible inside the blue resin. the resin has a blue hue with a greenish tint and pearly reflective texture.
top down view of the upside down cube. the bottom of the cube shows dark strips of LEDs in the background, while some cables and the Arduino are visible as a black silhouette in the foreground. behind all this is blue LED light shining from below. the surroundings are dark.
