In the spirit of 3 Stooges.. how about some animation where you can donate x amount of DC Dollars and in return some Troll with your avatar in place of its head, pastes Mouser with a cream pie?  

Coding such a thing is beyond my experience.  I would think some kind of gif animation?

The ultimate idea would be a DC meetup. Not saying it's realistic though

What about a game where a winner gets a signed (by Mouser/or whoever the boss is around here) DC's logo pic?
What about a game where a winner gets a huge cake with 10 Years of DC written on it?
What about an origami contest where a winner (an origami, not the person who made it) becomes a base for the new logo?
What about a game where Mouser and others make a software (released on Anniversary day) where winner's name is included in the name of the software? Like X's torrent client (where X is the name   ) (or at least a winner can propose a name of the software)?

I like the idea of a special 10th Anniversary Mug. 

Perhaps it could feature a drawing of Cody with a long beard and walking with a cane, showing his age. 

Hello !

Cody is just 10 years old. What is he carrying a cane for ?

He is a hipster.

How about something like a special print issue magazine featuring a lot of the cool stuff that has happened over the years here at DC?  Edit it like an actual publication and allow people to purchase it (So it doesn't end up costing mouser anything to provide).
