Wide angle lens adapter

This is an iPhone fish-eye wide angle lens that fits in a housing posted on Thingiverse by Kwatters. It is intended to be used with the Hercules HD Twist but will probably work with any pinhole style camera and maybe others, too. I purchased two of these on eBay for $5.21 each. The housing fits perfectly on Gael's Rev 2.0 eye mechanism. I haven't decided if I'm actually going to use them yet as the view with Google Cardboard or an Oculus-based device is completely overwhelming and InMoov tele-control is on my bucket list.
