Where the 2D Sidewalk Ends

Have you heard of this 3D sidewalk chalk stuff? I wanted to try it out, so I went to Target to procure my very own set. Seven dollars seems a little steep for five little double-sided chalk sticks and a child-size pair of 3D glasses, Crayola, but dang it, now I'm so curious about the whole thing. And here I am in freaking Target. So I'll bite.

Now I'm ready for some serious sidewalk fun. Aside from being double-sided and sharpened at each end (fancy!), the chalk looks just like regular ol' chalk, so the magic must be in the glasses. Crayola's website says that warm colors like red will appear high while cool colors like blue will appear low. Sounds good - I'm off to flex my sidewalk art muscles... as soon as the sidewalk dries from that little gust of rain we just had.
