For those interested in the stereoscopic versions of my animations.. A friend of mine shared this link with me.
The cheapest option is using the cross-eyed version. Just cross your eyes until the two images merge into one stereoscopic image. The problem is some people are not able to cross their eyes to view that; or they cannot do it for extended time. Me, I can do it for a long time.. From practice I suppose. :)
The link above has a cheap device that works like Google Cardboard, except it does not require a portable display device like a mobile phone. This one is for viewing VR animations directly from your monitor.
It has lenses in it and you have to hold your head perfectly still as you look directly at your monitor. Sounds like a pain to me but some of you who cannot cross your eyes may enjoy this option.
He also said the strap is extremely cheap like a rubber band and it broke quickly. But he can still use it by holding to his face. It also folds flat for convenient storage.
It's the Pixi 3D viewer; $5 + $1 shipping.
