take a raw .ppm file with an image, run it through here: http://tomeko.net/online_tools/file_to_hex.php?lang=en Deselect both "Use 0x and comma as separator (C-like)" and "Insert newlines after each 16B" and get the raw hex text. copy all of the text and paste it into the input box on the scratch thing. wait 5-10 seconds WITH TURBO MODE ON and it should draw your image!
all my code. uses a whole lot of scratch trickery, probably my last project that I am going to make.
