GRIDZ

Initial sets would come in several different colors, and there could even be separate packs of colored tiles to use with existing sets.

Each set is one module. Connect multiple modules horizontally and vertically to make larger grids for bigger creations.

Unknowns
I'm not sure how many pixels should be in each module: 5x5, 6x6, 10x10, etc. Maybe there's a way to figure out the minimum number required to make alphabetical and numerical characters for example. Then the instructions with the sets could show how to arrange the pixels to make certain characters in various sizes.

There is a need for an enclosure that I could not create with the pieces in LDD. Each side should be the proper thickness so that when modules are connected to each other, the pixels appear continuous. I envision the enclosure as two pieces, a top and a bottom, that snap together in the middle. The sides would have holes for pegs to allow connection to more modules. Below is a mock-up of how the two pieces might look and connect, along with some modified connector pegs. (To save plastic, there could just be a bottom, two sides and a top, then have the back made of cloth or even a piece of cardboard from the packaging.)

I would also like to have a tighter-knit collection of pixels, but it would become difficult to spin them with your fingers. A triangular piece with a hole in it may help, and it would allow two colors per pixel, though it would be trickier to switch to other colors.

Conclusion
This is a different way to think about using the creative power of LEGO. Actually snapping the pieces together is only the first part of the creation process. Then comes figuring out what kind of shapes and images can be formed. I see them as something you could put on your shelf at home, or set on your desk at work...just think about the possibilities of recreating classic 8-bit video game characters! There is also a certain educational aspect to the grids as they replicate on a basic scale how computer screens and digital signs work.
