[jQuery] tables and chairs app

[Jack Killpatrick]

Hi All,
I'm thinking out how to put together a web app that allows a user to 
have a "room" and in that room, place tables and chairs, which will then 
be used for a scheduling app. The scheduling part I'm on top of. The 
graphical part for positioning tables and chairs is what I'm looking for 
a good solution to.

At minimum the user has to be able to drag/drop and rotate the tables 
and chairs, to position them in a way that resembles the "real" room. 
Ideally, they should be able to either resize the table (drag sides of a 
rectangle or enlarge a circle) or, less desirably, I could give them a 
set of different tables to choose from (or both).

Right now I'm thinking of using canvas and looking into jQuery plugins. 
Any pointers?

Thanks,
Jack
