Guest post from Emma:

We walked around town to find eight Dinky Doors. The Dinky Doors are little structures that are hidden around Cambridge. We have found all of them, which is really fun. We have quite a few near us. This one is the closest. It is a bird's nest with a little elevator, which you can move up and down.

The second one we found was the Teleport-O-Matic from Dr. Who, which was between two phone booths.

Next we found the Emailerator and the DFO -- Dinky Door Flying Object -- on the same street.

The funniest one of them all was a door with a present left outside for Mr D Mon, from an angel named Angela. You could see the demon's hands and tail sticking out of the door.

Next up was the Wonder Emporium, which had shelves with little things on them, like marbles, a Lego character, and dice.

We're not really sure what was inside 10 and a quarter Downing Street, but it was still funny.

Finally, at the bottom of a lamp post in the middle of Parker's Piece, we found the Reality Checkpoint -- or really an elevator.
