I do like the projector’s animation, though I wonder if the rotation isn’t a bit strange for such device. Still, that model looks pretty cool, and I like the color variations for each part, it looks already more complex than the original model from HL.
But now there might be a big issue for the hologram movements (for when she demonstrates jumping over pipes, crawling and swimming). Even in the original map that was way too unrealistic, so the only way I can think of is like tracking projectors (maybe a smaller unit than the stationary one, but in greater number in the concerned rooms) that follow the hologram why it executes those movements.
