Information Density

No, I don't plan on outlining my entire novel this way. However, who can resist having a bit of fun with a new stack of index cards and a fresh ribbon?

The nice thing about these cards, I can be typing away on a page, come up with an idea to note for later, and insert an index card behind the paper, roll it through, type it up, and then pull it out without messing up the alignment of the page.

Who says you need a modern operating system to run two processes at the same time?
