I like to make my renders a little on the larger side. The limits of my current machine allows for a 10,000x3,000 render at better than medium quality (roughly 500Mb of frame memory). At any rate, if my renders are too large to be properly viewed, let me know and I will scale them down. If you would like to see larger ones, feel free to supply me with more RAM (and probably a better heat sink for my processor, too) and we'll see what we can do.
