Programming with MSPaint

I haven’t yet checked if this is real, but there’s no reason it can’t be; 1s and 0s are just 1s and 0s. It’d be easy to re-create, too, by changing the text in the file to any arbitary code you want then converting it to a BMP and loading the image in Paint. It’s a shame the BMP header data means the C won’t compile though; I can’t see how you can do anything about that.
