In a way, all 2D art is pointillism. Computer art is points of color information. A traditional painting is flecks of paint sticking to points of paper. Our eyes use a finite number of receptors such that our vision is the aggregate of all those points of information.

Tradtional pointillism is intentionally creating art by applying points rather than traditional lines.

The definitions blur with this example of using a computer to determine which color goes where. Instead of organically creating the Crayola image by individually placing the crayons to build the image from an outline and filling it in, it's more likely being created by unskilled laborers laying down the crayons from the bottom up based on a printout of the colors that need to be layed out in the frame. The computer created the art, not the person placing the crayons.

If there were a plastic lattice frame where crayons could be placed into predefined holes, it would be possible to create this kind of art without the aid of a computer. Trying to do it, without something to hold the individual crayons in place, would be physically more difficult. Anybody who has put all the crayons back in a box knows that the crayons don't line up parallel, so it takes some fiddling to get them all to line up together to fit well in the box. It wouldn't be impossible, but then it's a matter of fighting with the medium.
