This is what I am picturing so far:
A guy (your character) walks into an outhouse, when you walk into this facility, you discover a giant laboratory containing both a server farm/cluster and a supercomputer! You walk up to these systems and notice 2 identical electronic signs displaying "Now Serving X Clients", where X is the number of clients that the system is currently serving (duh). You also notice 2 other identical electronic signs displaying: "Cost of system: Y", where Y is the amount of money that the respective system costs.
There are 2 levers in the center of the room, one of them increases the number of clients for both systems, and the other decreases it. When the number of clients is increased (by you of course), then the cost sign for each system will go up as well, but only if the new number of clients exceeds the capabilities of the system. So the goal here is to show the player that server farms/clusters can be much more cost effective than giant supercomputers.
Any other ideas? I'd love to here what you guys think.
Oh, and I checked out SDL the other night and I got some images displayed on screen with alpha blending and colorkeying in no time! [smile]
I can almost hear the kinks turning in my head (needs an oil change, hehe [grin]).
