When the more advanced of my students encountered the widget for encoding B&W images and then got the freedom to be creative with producing an image to submit, some REALLY interesting things happened! One of them started with the digits of pi (3.14159… but without the decimal character), set the widget to maximum width and height in hexidecimal mode (FFxFF), and then did a huge copy/paste of the digits of pi (retrieved from some online source) into the pixel data area of the widget. The result was a highly random-looking batch of B&W pixels… and became a picture of a HIGHLY accurate version of pi!
Another student started with an MP3 file of the song “American Pie”, opened it with a text editor, captured a portion of the unintelligible junk on screen and dropped it into a utility to translate all the characters into ASCII values and then into Hex… which he finally pasted into the widget to produce a still-frame image of mostly-random-loooking B&W pixels that he submitted in a PNG image file named American_Pie.PNG.
I love the creativity and exploration they’re doing even if the resulting images are not immediately recognizable!
