Here’s a cartoon the Reverend couldn’t resist introducing to the fourth dimension this morning.
1. Use red/blue 3D glasses. View one eye at a time to see two different pictures.
2. If ‘b4’ is green or blue you need to look through the blue lens to see the Before picture. ‘afte’ will then be red so you look through the red lens to see the After picture.
Ideally 4D pictures will have some 3D effect when viewed with both eyes. Unfortunately this one doesn’t.
Here’s another version. This time ‘b4’ is red. Let us know which you prefer.
