I don't see how it could be that hard to make ourselves. There is no gas/electrical technology going on here, just a projection on a spinnnng screen. Then you make a breadboard to convert the signal. Would require some work and research, but not nearly $40,000 worth.

I think you misunderstood it...It is not a holodeck at all, it is just a projector like what we have already on a spinning screen...you'd keep getting whacked if you try getting into the image...
