I just watched the Toy Story 4 trailer and was surprised to see Pixar had added a couple of insulators in an antique shop scene.

This image is Pixar's take on a 3D rendered insulator, cropped from a frame from the trailer. (It's around 1:15 into the trailer.)

If you'd like see it in the video yourself, check out the link below or just search the recent Toy Story 4 trailer on YouTube. (Forgive me if this breaks any Picture Poster rules.)
