Oh Yeah!" is one of the best optical illusion quilts Dave has ever designed.  It's two colors, all of the blocks are the same size, no curves, and...it's NOT paper pieced.  Dave found a computer generated image and deconstructed it so that this mind-blowing illusion could be made into a quilt.  Its construction is very similar to one of the first quilts he made which was strip pieced.  And don't worry about getting dizzy, that only happens when the construction is complete and you take 3 steps back!
