I recently rediscovered Brian Eno and Peter Schmidt's Oblique Strategies when they were made available as a Widget for OSX Tiger's Dashboard. These "one hundred worthwhile strategies" are a lot like Zen Buddhism's koans - only with fewer religous overtones. You can get your hands on a hard copy via Eno's online shop, or check out several other digital versions. I've got to admit, I put them to use on some new business I'm working on, and they definitely helped get the (mental) wheels turning. You business types out there might employ Oblique Strategies to arrive at the proverbial Purple Cow that Seth Godin is always talking about. Or you could carry on being unremarkable.
