I didn't know if I should believe you so I had to check and found you aren't kidding. That's pretty hilarious to me.Quote:

Acrylic on canvas 48x36 inch.
I used LaserBoy in the design process of this piece.
I actually designed the elements back in 1986. I got some isometric ruled graph paper and flipped it over on a tracing table so I could see the lines through the plain white side of the paper. I used a steel ruler and some Sharpie markers to make a set of nine originals and photocopied them 72 times each. I cut them out and glued them together into this:

The piece that I just completed (Frank Laid Flat) is the same 9 elements laid flat with colored backgrounds.
I recreated all of the designs in CAD, saved them as a DXF file, opened that in LaserBoy, exported a high resolution bitmap from LB and colored it in in a raster image editor.
Then I printed exact to scale 2D rulers to lay it out on the canvas.
The solid colors are painted with liquid paint and a brush (inside of masking tape areas) and the black was done all in one shot with flat black spray paint (also with a lot of masking tape).

This version of LaserBoy introduces something completely new.

LaserBoy ASCII math forms!

math frequency_mods

math frequency_mods_xyz
Each of these take parameters in a specific order from text and render into LaserBoy frames.
All of the math is done with double float and scaled to 100% of signed short int space.
Animations are written as two sets of identical single forms.
LaserBoy does linear interpolation between them to create all the frames in between.
See:
./LaserBoy/txt/math.txt
To open this file
i to import
4 for txt
math.txt
1 to replace frame set
Each form is a solid color.
For better effect,
g frame to palette trans
up arrow 5 taps to the palette of pure hues.
C (capital) to set all frames to use this palette
^ (shift 6) to span the palette through the vertices of all frames
[Esc] back to main and hit
` ( or ~) to play the frame set
Enjoy!
cool!
can you post some pics / video of the math frames?

Take a look at math.txt.
It's pretty easy to create some insane abstracts.
