OOTW Easter Eggs?

[tribby@cup.hp.com (Dave Tribby)]

I've completed the game Out Of This World. I had to concentrate on
avoiding rocks, creating shields, zapping bad guys, jumping over nasty
plants, etc., and did not notice anything I would call an "Easter Egg"
in the program. But I've heard that there are some. If anyone else
knows where they are, please let me know. (If you post them to the
net, you might want to put a "SPOILER ALERT" warning in any
descriptions that give away too much of the game.)
