This is a quick calculator for those of you with backburner render farms. It'll estimate how many frames your computer will render versus how many your idle backburner nodes will in a given amount of time.
For example - say you work at a small studio and have a dozen backburner nodes available. It's Friday afternoon, you want to go home but you're concerned that the new glossy objects increased your frame time to 20 minutes / frame on your workstation. But how many can you render on the farm? This tool will help you. For the type of work I do this tool works well - your mileage may vary.
