One package has arrived

from Sculpteo.  Funny how the company in France was able to print and ship these before the company in the US.  Anyway this is what arrived in the package:

These look good, if a little smaller than I thought they would be.  I like the way they stack, but the tabs and holes are working quite as well as I had hoped for the alignment of the blocks when placed on a 45 degree corner.  Have to see how the Shapeways ones look...
