This software is similar to its original implementation in Processing with the benefit of increased resolution in time and space. The image is scaled to fit the full screen and has an increase in frames displayed per second due to the speed of C++/OpenGL. These benefits create qualitative differences that alter the perception of the work. I was shocked to see this version of the structure running for the first time.
The negative aspects are the difficulty of implementation and the fact that the software must be run on a local machine rather than over the Internet. The equivalent software written in Processing only required one file of 118 lines while the C++/OpenGL version required 3 separate files with a total of 224 lines. A different version of the software must be created for each operating system, which also takes extra time and testing.

It's an amazing thing to see this program running full-screen at 1600x1200 pixels and in real time.
