What I’m thinking

Weird, but you do you!

Why limit yourself?

Id copy the entire thing to a separate place where I keep installed programs and keep the torrent files untouched to seed from. It’s 1 gig, you can spare that right?

Depending on the relative direction of the light and “camera”, the click point could vary. It wouldn’t be on the tip of the shadow unless the shadow was already directly below the tip of the pointer in line with the line of sight. More likely it would fall somewhere “between” the apparent position of shadow and pointer before clicking.
