When the whole VR craze was beginning, I noticed that the Google Cardboard template was open source. I wanted to show our clients that we could create custom VR viewfinders if they needed them, and also just to get the experience going through the process. This was really helpful in sales meetings and showed certain clients what was possible, when I showed my demos on the phone through a low cost, branded VR format.

If I were to do it again, I would buy cardboard that is white on one side, for printing, and black matte on the other, to reduce reflection.
