Hello,

   I have put together the cryptopunks gem v1.0 [1a][1b] that incl. a
command line tool that
lets you mint your own 24×24 pixel punk images off chain
from the True Official Genuine CryptoPunks™ sha256-verified original
10 000 unique character collection;
incl. 2x/4x/8x zoom for bigger sizes.
   Example from the readme:

Use the `punk` (or `cryptopunk`) command line tool. Try:

$ punk -h

resulting in:

Usage: cryptopunk [options] IDs
  Mint punk characters from composite (./punks.png) - for IDs use 0 to 9999

  Options:
    -z, --zoom=ZOOM        Zoom factor x2, x4, x8, etc. (default: 1)
    -d, --dir=DIR          Output directory (default: .)
    -f, --file=FILE        True Official Genuine CryptoPunks™
composite image (default: ./punks.png)
    -h, --help             Prints this help

Now let's give it a try. Let's mint punk #0, #2890, and #8219:

$ punk 0 2890 8219

printing:

==> reading >./punks.png<...
     >ac39af4793119ee46bbff351d8cb6b5f23da60222126add4268e261199a2921b<
SHA256 hash matching
         ✓ True Official Genuine CryptoPunks™ verified
==> (1/3) minting punk #0; writing to >./punk-0000.png<...
==> (2/3) minting punk #2890; writing to >./punk-2890.png<...
==> (3/3) minting punk #8219; writing to >./punk-8219.png<...

And voila!

And, Yes, you can use cryptopunks in your own scripts too.
Example from the readme.

require 'cryptopunks'

# step 1: read True Official Genuine CryptoPunks™ composite image
punks = Punks::Image.read( './punks.png' )

# step 2: start minting

punks[0].save( './punk-0000.png' )
punks[2890].save( './punk-2890.png' )
punks[8219].save( './punk-8219.png')

# or change the zoom factor
punks.zoom = 4   # use x4

punks[0].save( './punk-0000x4.png' )
punks[2890].save( './punk-2890x4.png' )
punks[8219].save( './punk-8219x4.png')

Happy minting. Cheers. Prost.
