It's a color printer! Using photon stacks and a powerful new single-chamber particle ROM based on the latest particle-order manipulation paradigm.

    I used to crochet while waiting... LOL

    Internet has been slower.

    Actually, the question mark shouldnt be there, i was just pointing out. And this printer is very cool indeed :)

    So, as it uses a particle palette, it can print basically any TPT "stamp" inside a 128^2 grid?

    @Damian97 You assumed right! :D

    I see. Assumed that the building of circle comes from here

    @Damian97 The squared distance of point (x, y) from the center of the image (WIDTH / 2, HEIGHT/ 2) is (x - WIDTH / 2) ** 2 + (y - HEIGHT (oops) / 2) ** 2). This line sorts the pixels according to their distance from the center, then reverses the order so that the furthest pixels are drawn first, so you get the shrinking circle effect in the second-to-third image transition. Here, pixel positions are denoted by a single number i = y * WIDTH + x, so there's a bit of gymnastics to recover (x, y).

    Studied your script. Most of it is pretty much understandible, however img3order = reversed(sorted(img2order, key=lambda i: ((i // WIDTH) - WIDTH / 2) ** 2 + ((i % WIDTH) - WIDTH / 2) ** 2)) gives questions. Mind explaining a little it for me?

    @apple5265 First, find an image, crop/resize to 128x128 and save as png. Then use something like https://ptpb.pw/Vh1K to convert the image into printer commands (that file is specific to the demo). Then use https://ptpb.pw/Zku0 to import the printer commands into powder toy: first, clear any existing photon stack and reload particle order; then call "loadfile.lua('import_phot_data.lua'))(x, y, commands_file)" where (x, y) are the coordinates of the photon stack.
