is it a watch and a sun dial?

nope. but close. XD

No one wants to guess? Ok i'll give you a hint.

Maybe the thousands of moving parts don't have to be mechanical? huh? anybody?

A robot, and a living person? XD Oh. Wait. They both have thousands of moving parts...

A cell phone and two cans connected with string?

Spud- cant a string and 2 cans move?

A sun and a light bulb?

No, no, no. *shakes head* ;D

A clock and a calendar?

an hourglass and a sun dial?

Yes! an hourglass and a sun dial. Congrats!

darn! I was close ;)

Oh, btw can i just point out that technically they do not have the same function. A sun Dial is used to tell the time, but an hourglass is used to measure time. you wouldn't be able to use an hourglass to work out the time.

Drat! For being in all the top levels in my classes at school I somehow land short of answers every time...

oh well. the question was answered before i even got here.
