There are a couple of HoloLens developer groups on Facebook. One of the groups has ran a couple of challenges. The current challenge is to create a Wizard Battle. This challenge ends on August 23rd. I may do something else with it, but if not, it was a fun diversion.
I’ve been posting HoloLens videos weekly for a few months now. If there is something you are wanting to see let me know and I’ll see what I can do. It seems more developers are getting their hands on the devices and are posting videos. It is great to see what everyone is doing.
Again, let me know what you want to see by leaving a comment either here on the blog or on YouTube!
