Every thing you create in Trangles+ is actually a many sided Polygon. For example a triangle has 3 sides however a circle has (in our case) 100 sides. A "Trangle" refers to each polygon that will make up a Trangles Image. Using Trangles+ will challenge and at times frustrate you, while bringing your creative self to the forefront. This software started 6 years ago as a diversion from my programming work. Today it is a fully feature app. supporting saving and open files, copy, paste and undo among many other features. I hope you enjoy it as much as I have creating it... now go spend some time with your creative self!
