Cool Video Prodution Widgets for Your iPhone or Laptop

I often find I have too much information to remember (and for some reason people expect me to be able to spout pixel aspect ratio numbers like a multiplication table). Fortunately the fine folks over at Digital Rebellion has solved this (and for free). They offer several video widgets that do important math, these run on a web browser or iPhone (and a couple can run offline as well).
