Gremlins Easter Egg - Let's Do the Time Warp Again

This happens a little bit before the eggs hatch when the dad calls from the convention and the mom's making christmas treats. While watching the dad, notice there's a large machine in the background with several gadgets moving on it. The scene cuts back to the mom, then back to the dad, the machine is gone. The machine is the one from the movie The Time Machine. It charges up, and disappears.
