Excellent! Laser + maze = entertainment. I wonder about lasers in machine tools though. Probably should include those used in 3D printers too. I wonder if the presence of lasers in these devices is "entertaining" to the user. Likely interesting, but I wouldn't think entertaining like the other applications above. Probably then need to include laser levelers, laser measuring tools, and tools with laser pointers in them like drill presses, thermometers, and saws, and I don't think the use of lasers there is "entertaining". But that might be just me.
