In this phase (first prototype) the project is developed with 4 breadboard that I have join to have a good area to work. 

I play with wiring a bit to define the XY array. I want at least 3cm between every point. That means 8 rows and 5 or 6 columns. It's enough for this prototype.

In Z axis I need a suppor for LED strips and diffusers. I think that seven LEDs are a good quantity for each  support. I have designed a piece and print a bunch of them to testing.

Also I have designed several diffusers to print with transparent PLA and transparent resin. With square and hex shape, fully solid and hollow. I'm testing all of them to see the best result.

More info soon, work in progress
