This is a preliminary version.
I'm waiting for some new bricks to come out, so I could change the A,C,H,I,U,g,y etc.

Thank you guys. Actually, I did not expect much attention. I simply wanted to secure these shapes as part of this design.

@djnippa: Thank you for the Brick Stacker tuto. I didn't know about this technique until it resurfaced on FS Live. It could have helped me out many times. The bricks I am waiting for are the same ones you've suggested on the same thread: white half circle on black.
