We’ve seen a flurry of technological innovation centered around image search, particularly in the form of artificial intelligence algorithms that can automatically tag images to make them more discoverable. After all, it’s no good to have a massive collection of digital assets if no one can find what they’re looking for.

Now 500px is getting into the game with something rather unique.

It’s called Splash and it’s a tool that lets you search for images by drawing out a rough sketch of what you’re looking for.

You start with a blank canvas that looks like this:

The slider on the top right lets you adjust brush size while the color box on the right lets you switch between a color palette. Below, images are instantly populated into several categories: landscapes, people, animals, travels and cities. As you add color and design to your sketch, the images change in response. It’s pretty incredible.
