Vector artwork poster - 17 years in the making

This whole thing started with an exercise in one-point perspective I had to draw for my 8th grade art class....in 1997.  I was 12 or 13 when I drew this in colored pencil.

Then, a full decade later, I brought my art into the new millennium with a computer vectorization...with nice crisp lines and clean gradients.

...then in January 2014 I started playing with colors. I added some cool space-age laser beams and went for a warm vs. cool color scheme. I always liked the interplay of warm oranges against cool blues.

...Then, finally, I settled on a unified color scheme and made this TRON-esque tour de force in geometry, which I finally settled on a name for...
