Back in 1978, I created the "Question-Mark Bird" (shown at left). I liked this design because it requires the viewer to adopt a creative frame of mind when looking at it.
For example, seen from one perspective, the design looks like a bird; from another, like a question mark; and, if you turn it upside down, it looks like a seal bouncing a ball on its nose.
I've used this design in various places: in my books (A Whack on the Side of the Head), in the Creative Whack Pack, and also as a some time logo for my business. You might say that this design has "worn well" through the years.
You can imagine my surprise (and delight) when I recently discovered that a certain Roy Blumenthal, a South African artist, liked this design too — so much that he tattooed it on his arm!
I'll let Roy tell the story in his own words:
"The folks over at MISSING LINK are offering their buddies and clients a free tattoo. This threw me into a panic. And I quickly pulled out one of my
favorite of Roger von Oech's WHACK PACK cards... 'Solve the Right
Problem'. I love this image. I copied von Oech's question mark into ArtRage, and started messing
around with it. The red/pink background is meant to represent skin tone." [shown at left]
So, here's Roy's finished tattoo.

This is what Roy said about the process:
"This didn't hurt much at all. It was more of a sort of vibrating vague sting, that numbed out after about ten minutes. When the colors settle, this will be a very painterly piece of skin. It's not discernible now, but everything is blended and shaded and graded. I'll post a pic in a week or so, when it's looking more like it ought to."
Roy also made a series of short videos about the tattooing process which can be found here.
Good luck with your tattoo, Roy! Tell all your friends who like it to go to creativethink.com!
