Did something pretty fancy on the web page for my #vcfse exhibit: on desktop it shows photos of three computers next to each other, but on mobile it shows totally different photos: individual photos of each computer.

This is because, since the computers were so close together, in cropped photos you can see the computer to the left and right, and that looks weird on desktop.

Not the fanciest CSS, just not something I've had the need to do before!
