As most of you know, we have two Ruby Quiz problems left (http://groups.google.com/group/comp.lang.ruby/msg/6f46393932c22e49 
).

I haven't picked them yet, so now is a great time to send me any  
terrific ideas you've been sitting on.  I'm looking for a pair of  
great little challenges to end on, so pull out all the stops and send  
me the good stuff.

Thanks.
