Knitted Scarf - Keyboard illusion

Just finished a fun knitted scarf.  The pattern is actually an illusion - from an angle, it looks like a piano keyboard, but when you look at it straight on, it just looks like black and white stripes.  It was really easy, just have to follow a chart for the knits and purls.    

The pattern is named Counterpoint and was found at Jennifer Crawford's Knit One, Purr Too blog.   Looks as though she is no longer updating that blog, but there is a link to her Counterpoint pattern, available on Raverly.
