Contrast

"Giant constrictor snake squeezing complete Copenhagen citybus."

This is an advertising campaign in Denmark, advertising a zoo!  I think the snake squeezing the bus really works well and looks so obscure that it attracts your attention.  The snake is so large that it shocks us and it makes it interesting to us.

I think this doormat scale is bad design, as the contrast of the materials from what we would normally use for a set of scales is so different.  The texture and the colour make it feel ugly, although it does indicate us to put our feet on it as it is a doormat.  I think it is interesting but not a good piece of design.
