Earlier this week we brought you a story about a man who is making a video game that is laid out across four spatial dimensions. It's a platformer. But what, we had asked him, about a 4D racing game?

In the blog post it is explained in a way to say that we as 3D beings can’t perceive a 4th dimension, much like a 2D object living in a 2D world can’t perceive the 3rd dimension, sort of like Fez.

Keep in mind that 3D and 4D ultrasounds are not typically used to diagnose problems with your baby. Also, getting an ultrasound at a commercial center is not a substitute for medical care.
