Motif Mask Kaleidoscope Puzzle is a lot like Art of Perception: Ravioli from just a couple of months ago.
  The object is to quickly stack the stencils to match the given image.  What I don't like is the timer.  Sorry. But the patterns look cool.
Factory Balls is another stencil puzzle which was quite popular  about a year ago.
