Sharpie Liquid Pencil
Writers, artists, and Bible note takers take note. Sometime next month (9/10), you will be able to purchase a Sharpie Liquid Pencil. I have a fascination with pens and inks, and I like most everything about pencils except the feel. Problem solved.
Apparently the liquid graphite ink is erasable but becomes more permanent over time. It looks and sounds pretty cool.
For more info, see the Sharpie Blog post referenced above, or the Crave blog post, and a CNET review. And another post on Wired.
