The w key.
 

I just found something I don't know if it is on purpose or not but when I hit the w it changes the whole thing to black wire frame.

In every version for the past 9 years.

This is the Wireframe feature. It's used A) for entertainment and B) to prove to people that the Aquarium is not a movie. :)

Also if some guy is seeing weird stuff in the rocks he could ghost bust them. :D

Is this also a program you used to lay out the original scenes.

I used Lightwave to create the 3D models.

Dream Aquarium has the "Wireframe" feature too.- Weird and fun.
