Late to the whole Google Cardboard party, but just got a cheap knockoff Cardboard myself. The seller didn't know the specific configurations, so I just went to check around.

I found the Viewer Profile Generator[1], but it was completely non-functional, generating blanks instead of valid QRs. A StackOverflow post[2] explains how the website generates them, but I found it tedious to replicate.

Hence, I built a site in Vue to both practice, and iterate the profile generation faster.
