I have a 20 month old baby girl that sits in the front with me when I drive. She has been watching the empeg boot for a while now, but yesterday she waved back at the waving penguin and said 'hi' to it.

Awww, thanks, that's so cute! (/me gets a warm fuzzy. )

I waved back at the penguin (as did some of my passengers) from day one. It was the intended effect when I created that animation.

The waving penguin is the only reason I haven't installed hijack yet, and it looks like it's paid off.

As was already stated elsewhere in the thread, you can put the original waving penguin back after installing Hijack. Instructions on how to do this are here, and my original animation file for the waving penguin is here. Just load that into Jemplode and send it to Hijack.
