I fail to see how that's digital
Well you said it not me.
FTA: A 'laser beam' apparently has a few components. The "analogue" way - two mirrors on each end of the device. The "digital" way - replace the one curved mirror with an LCD THAT HOOKS UP TO A COMPUTER. The computer controls the LCD (orientation of the liquid crystals) and ultimately affects the laser shape. I'm amazed that they can use an LCD instead of the mirror..
PS: FRIGGIN' DIGITAL LAZZZZZERS!?!?!!
