why is today reminisce about projector day?

I used the OG steam controller when I had a projector setup, I'd turn my office chair (that I used at home) around to look at the wall instead of the computer and use the virtual keyboard/mouse for films or watching stuff, or even playing games. Although it did take a lot to adapt to some which I preferred to use a regular controller. I forget if it was Just Cause 3/4 I played the shit out of with the steam controller or something else.
