Create a memorable mosaic

We have a 32 pixel high x 120 pixel long canvass. I would like to see a memorable mosaic created in 45 seconds of animation. The use of color is important, please avoid black. The canvass starts blank and people will be guessing what you are building, and they will be pleasantly surprised when it ends. The process of building the canvass pixel be pixel using color, motion, shapes movements, scrambling is important to grab the attention of everyone watching the canvass. How you animate it, create it, build it, is left to your creativity. (You can google Tetris images to get ideas, but not limited to that) The final deliverable is a .MP4 format clip in 45 seconds to 50 sec, the last 5 seconds the clip will scroll left to right. We will display the clip and it will scroll around the outside of an oval shape trade show booth. No one can see the entire 10' high x 60' wide display from one view, that is why it has to scroll at the end. or if possible scroll while it is being built. (That is a technical part, left for the you to decide). The end mosaic, needs to be bold. It can be a graphic, object, person, photo, place, but it needs to be memorable.
