Monochrome TI calc pride flags
It's a design I made for TI pride flags. There's one for each model of TI monochrome graphing calculators with flash app support.
Each of them checked flash apps and the OS for a RSA-512 signature, so you couldn't easily make your own without a license from TI. However, everything changed in 2009 when Benjamin Moody factored the key for the TI-83+, and the community quickly factored the others.
The flags shown here have been derived from those private keys.
How to read
Basically, it's a grid of 7x3, each of the cells' 24-bit color, read left to right and top to bottom, reads 24 bits of the value of d. The last 8 bits is encoded in the sine wave's color in 8-bit greyscale.
