Ok guys, maybe one of you old school ninjas (and ofcourse our one magic one) can help me out...

In one of my engineersing courses I have to read the DaVinci code...(who knows why, since I am studying to be an electrical engineer, but I'm not complaining, I enjoy reading).

I have to make a physical clue that could fit into the book...(something along the lines of a cryptex for those of you who have read it)...not necessarily a safe like the cryptex, but just any clue, and I am fresh outta ideas...

all I can think of is a paper mache goblet with the letters of Louvre written underneath it...and thats a crap idea...

So please, can anyone help me with a few ideas?
I gotta have this thing made by Monday...and its Thursday night now...


this is a call for Help! I am rallying the forces, and hope to be met with enthusiastci resopnses.
