actually this was the hardest part, how to make numbers look thick and REAL, and connected. Here is a GIF that shows this nicely:

Thats the reason why i had to work with ferrofluid and change its structure and composition, i wanted to have thicker numbers. Whole screen is 10mm thick inside, and numbers sometimes go up to 8mm of thickness. They are especially nice from the angle because the seem like they float and not simply stuck to the wall. I will make better photos definitely.
