Thanks for that. When I worked for Mark Zimmer and Tom Hedges at Fractal Design Corporation in the early to mid-1990s on what is now Corel Painter, they were enamored that on my first day of work I had built a test suite for the printer drivers and was isolating bugs in it. Afaik Painter was the first software to come in a paint can, and it was the first commercial software to realistically simulate the effects of real media, such as paper gain, ink bleed, stylus pressure (employing a Wacom pressure tablet), etc.. The core algorithms were often written in Motorola and Intel assembly code and were entirely undocumented. I remember I isolated a bug in the some undocumented, convoluted, nested algorithm which unraveled the paper grain relative to a brush model, and doing so not by understanding what the function was doing precisely but by reverse engineering the state machine (totally in my mind, no written notes) and using induction to narrow possibilities. In short, I often see possibilities that others do not. I am able to build an elaborate imagination of a design or issue in my head. Put it another way, I have a vivid imagination and it is known that my IQ is concentrated in the visual mathematics realm (I loathe details that I can't handle in my head that have to written down).
