This script will make a grid of circles. You input the diameter of the circles, the number of circles in the X and Y directions, the space between the edges of the circles, and if you want the circles in a rectangular or a hexagonal grid. The two attached images show pictures of the default rectangular and hexagonal grid created by this script. The circles and background can be any colors. This script could be useful for selection masks, making pictures of bubble wrap, or lots of other things that I haven't thought of!
