Hey
Looks great!
Would also like to have a 32×32 Grid.
There was a kickstarter, but it has no seperate pixels like Jeremys frame.
And i really like the seperate, milky pixels.
Perhaps instead of using a very expensive big cutom pcb u could just use some of these.
I think jeremy is using them as well:
