Skewer Project comparison

I chose to compare my project to Erica Anderson's project.  The sticks in mine cross at each end forming parallelograms out of the spaces between the sticks.  While my skewers actually touch, the skewers in Erica's model only appear to touch.  They form a couple of optical illusions.  One is with the crossing of the skewers.  They are twisted in a way where they appear to be crossing.  The other is that the skewers appear to be curving.  They are actually still straight lines.  However, in both there was the grouping of the paper.  I put two pieces together with two skewers in the middle.  Erica had three pieces of paper in each of the four groups and speared on the skewers.  To show that there was more than just one piece of paper, Erica curled out the corners of the two outer pieces.  With Erica's model, you can turn it anyway and get the same basic view. Mine is generally the same way except that you could lay mine down and get a completely different view.
