I’m hesitant to describe a virtual reality experience as a “killer app” ever again, but I’m oh so tempted once more. I just emerged from a glimpse into the fourth dimension by way of a VR experience, and I’m still amazed and perplexed by what I played with.

My extra-dimensional leap came courtesy of 4D Toys, which went live on Friday on the iOS App Store ($6 here) and the SteamVR Marketplace. If you can pull it off, I strongly urge you to opt for the $15 VR version.

This immersive dive into the mathematical systems of a fourth dimension is actually a byproduct of a long-in-development video game called Miegakure. The ambitious game demands that players figure out puzzles by moving a character through four dimensions of space, all viewed within the confines of a three-dimensional perspective.
