Lair of Squid (HP 200LX) Easter Egg - HP 200LX Developers

On the HP 200LX palmtop, start the built-in ROM game Lair of Squid.
Type (without the quotes) "gallery".
You are transported to a hidden hallway, with portraits of the 200LX software developers hung on the walls. You can use the aursor keys to walk up and down the hall and turn to look at each portrait. The last one is a plaque with message of thanks.
(By the way, "Felix" was the codename of the 200LX.)
Exit through the door at the other end to restart the game normally.
