A filter that can create a subtle but interesting effect has to do with motion blur. The faster and closer to us things move in the real world, the more blurred they appear. And with the right filter, you can recreate this effect on the screen as well. The circles moving in the hexagon below, for example, the faster they move, the more blurred I make them to mimic the feeling of fast movement.
I came across an example of a “motion filter” while seeing images being blurred while sliding across the screen in an image gallery demo. Since data visualization also often shows movement, I wanted to see what I could do with it.
Although the image below is just an animated gif. You can see the fully functioning version here
