If you decide to add some safety features to this, I have a few suggestions.

These are features that my current garage door has:
1. Up and down motor torque limiters.
2. Up and down end-of-travel limit switches.
3. Electric eye prevents people or animals from getting crushed when closing (I think you already implemented that on this scene).
4. A small hand-held remote control.
5. A remote digital keypad outside the garage allows entry when a 4-digit code is entered.
6. A light automatically turns on when the door is activated, and it has a delay of 3 or 4 minutes before it turns off.

7. There is a mechanical lock (I think it's called a vacation lock) that prevents the garage from opening. It is simply a metal jam bolt mounted on the door that engages a hole in the track which prevents the door from opening remotely or manually.

Thanks. That brings up some interesting possibilities. I could create a remote digital keypad that will prevent unauthorized use of this scene.

Good scene. when I put the baby under the closing door it opens when it hits the baby. Was this done intentionally?

Yes.

ezpz(fib)5 -- All modern automatic garage door operators have safety sensors that prevent the closing door from crushing children or pets (or drunk or careless or stupid adults).


addendum: What I stated is true for the U.S.A. Laws my be different in other countries.

That kid looks so realistic! Great job.

Thanks.
