This is looking wonderful y'all. Clean design. Great functionality. I think being built for the web on Babylon.js is an awesome decision. We're at little biased at NOWHERE though. ;)
Support is great! The tracking accuracy is astonishing. My students loved the Web based experience design environment and we are going to create a very good team project!
Hololink is easy to use and offers many possibilities to customize. Thanks to the good tutorial that pops up when you first use the app, you can create your first free demo in only a few minutes.
The huge potential for marketing and events is obvious.
I can only recommend anyone interested to give it a try, it doesn't take much time.
