I've released a new mini app! (And a new apps page.)
I realized that I have a growing number of small tools and apps on this website without an easy way to navigate to them. I've made a "Apps, Tools, and Other Pages" gallery page to help find something specific or just for browsing around. This new page can be found at the "four rectangles" icon in the header above.
As for the new app, I put it on a page called Click Counter. It's a tiny JavaScript app written with p5.js. It simply allows counting things in photos — just drag a photo onto the canvas, then use the mouse (or spacebar) to count things in the photo. The mouse can be used to pan and zoom. It's simple enough that giving examples seems silly but here are a few:
It seems like it only really works in desktop browsers, but I'd like to add touch device support someday.
