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.Originally Posted by james

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 Visible Portions Of Frank
James Lehman 1986
folded photocopy paper 99x49.5 inch
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).

Animated MATH!
This version of LaserBoy introduces something completely new.
https://laserboy.org/code/LaserBoy_Current.zip
LaserBoy ASCII math forms!
[single frames]
math rhodonea
math epicycloid
math epitrochoid
math hypocycloid
math hypotrochoid
math lissajou
math pendulum
math pendulum_sum
math pendulum_xy
math pendulum_xyz
math harmonograph
math harmonograph_3D
math amplitude_mod
math amplitude_mod_xy
math amplitude_mod_xyz
math frequency_mod
math frequency_mod_xy
math frequency_mod_xyz
[animated frame sets]
math rhodoneas
math epicycloids
math epitrochoids
math hypocycloids
math hypotrochoids
math lissajous
math pendulums
math pendulums_sum
math pendulums_xy
math pendulums_xyz
math harmonographs
math harmonographs_3D
math amplitude_mods
math amplitude_mods_xy
math amplitude_mods_xyz
math frequency_mods
math frequency_mods_xy
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?
suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

This is the contents of math.txt. It is only one example of each form.

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

apply the frame set effect 'echos'. Add as many trails as you can handle. Say yes to the color shifting.
Then play the animation on your screen.

I made a difference today.
Have plans for much more.
