How to plot a animation plot on a 2D grid?

I have a 21*4 matrix data which only contains 0 and 1. I wanna build a 2*2 2d grid that can change color following 0 and 1.( 0 is white and 1 is black) Each column in that 21*4 matrix repersents the data for 1 block in the grid. How could I plot a animated plot to work like a neon? Thank you.

Zhen - how is the data in the first column of your matrix used in the first block of your grid? Or do you read each row of the 21x4 matrix and populate the colours in the 2x2 grid, then pause, and then repeat with the second row, etc.? Please clarify.

The first column will be like 21 signals input into the the first block. Each data will make the block either white or black. Hope you can understand it.Thanks

[Geoff Hayes]

so you apply the 21 "signals" from the first column into the first block of the 2x2, then apply the 21 signals from the second column to the second block of the 2x2, etc. Is this correct? Do you pause between each signal "update"?

[ZHEN XU]

yes, each signal can pause maybe 0.1sec.
