Yeah! Let me know, when you find a tutorial on how to do these.

It can be made in a 3d-program by making a z-depth map and then simply take the UV for both the drawing and the z-depth map onto a plane from the camera. Then rotate it a little in both directions.

Thank you! When you're able to explain it in two sentences, it cannot be that hard. Maybe there is even a video-tutorial around or you're able to create one in the future. That would be amazing!

The thing is to make a depth map where white is the nearest and black is farthest away.

Like this:

Not that difficult with the ball-pen drawings.

Allright. I will try to convert photos of my designer toys as an experiment. Would be cool way to present them in 2d to look like 3d
