This program demonstrates recursion by counting the number of squares in a "blob". The squares are arranged in a grid, and each position in the grid can be either empty or filled. A blob is defined to be a filled square and any square that can be reached from that square by moving horizontally or vertically to other filled squares. This program fills the grid randomly. If the user clicks on a filled square, all the squares in the blob that contains that square are colored red, and the number of squares in the blob is reported. The program can also count and report the number of blobs. When the user clicks a "New Blobs" button, the grid is randomly re-filled.
