Changing light colors, pushing/pulling grabbed objects, and opening the door

Here’s what I’ve got so far!

You can use mouse scroll up/down to push/pull objects currently held. The step size is configurable.
The light inside the chamber changes from blue/purple to red as you add in more mass, and gets brighter.
The sign above the door grows brighter as you add more mass, to reveal one of the hidden objects.
Once you’ve got enough mass to open the door, the sign swaps from orange to blue and the door swings open.

Take a look at the scripts here:

That’s impressive. The lights are very effective.
