Let's face it, if you know what EVERY prop is in this picture, you're a nerd...I mean, I'm a bigger nerd because I OWN them all but you're a nerd for recognizing them XD
I figure with all these items, I'm pretty much ready for ANYTHING!
EDIT: OK guys, I decided to add what props are here.
The main biggie is the map they are all sitting on. THAT is the portal map from the Terry Gilliam directed film, Time Bandits.
Now in the dead center of the map is a curious brass device called an Omni from the short lived TV series Voyagers.
Behind the Omni is the exact replica used by the internet reviewer Linkara from Atop the Fourth Wall of his Magic Gun.
Below the gun is a strange key with a circular handle forming the letters O and Z from the 1985 film Return To OZ. This key opened the Kings store room where the clockwork man Tic-Tok was stashed away. It was sent to Dorthy while she was in Kansas on a shooting star by the Scarecrow.
In front of the Omni is a curious pendant of two intertwining snakes from the Neverending Story called the Auryn.
Then lastly of course, to the right are three objects from the classic Tom Baker run of Doctor Who of his Sonic Screwdriver, Tardis Key and Yo-yo...the yo-yo of course was used to detect gravitational anomalies.
