Photo Dash

Tap or press Space to jump. Pick a ball at the top; open your own photo in the Splash tab to run across it.

A photo becomes the landscape. Down each column of the picture, the strongest change from light to dark marks where its sky meets its ground, and that line, smoothed, is the track: a row of wooden planks. Your ball rolls along it by itself, a little faster each level; tap or press Space to jump the gaps, and catch the sparks on the way. Pick the ball: a glass marble, a steel ball, a floaty beach ball or a bouncy tennis ball. Each level brings another of the site's sample photos (real photos, or AI pictures by Ryan Kamp, made with ChatGPT Images 2.5), unless you opened your own. The 3D button raises the photo into a relief, its bright parts nearer and its dark parts deeper, and the marble keeps rolling on it. The photo is read on this device and never leaves it.

This link opens it in the Playground. To put it on your own page, add the element and one script tag. Every option.
