I had that same problem and did it like this:  basically, i mod 'days 
since epoch' over array size to get an array index that changes every 
day.

#get a list of possible resources to choose from, eg
@resources = Resource.find(:all)

days_since_epoch = Time.now.to_i/86400
@resource_of_the_day = @resources[days_since_epoch % @resources.size]

It means that @resource_of_the_day effectively changes at midnight 
(server time) with no need for scheduled tasks or anything like that.
