Design Wall this week

Single Block

This weekend DS informed me that there are 175 days until their wedding, and the design wall this week has the first several blocks for their wedding quilt! 

As a mechanical engineer, he has a mathematical predisposition, and has always liked the Celtic Knot and other twisting geometric quilt designs.  We looked at different traditional wedding blocks and several knot blocks.  Then my son got to work designing a block for their quilt that used three colors and when put together created interlocking squares that are reminiscent of a double wedding ring.  Here's what they look like so far.

Four blocks

 He did an excellent job of designing.  There are no set in seams.  The pieces are easy to make, sewing long 2" strips together and sub-cutting in to 3 1/2 inch segments.  Each individual block is 16 segments.   The overall design is similar to Plaited Block (Nancy Cabot) but without the half square triangles, though the individual block is quite different.

I haven't been able to find a block like it in any of my books, so I'll have to come up with a name for it.   Do you have any suggestions?   Or maybe you've come across this block before?

Most of the strips were cut a week ago, and are now sewn in pairs and pressed.  Hopefully piecing the blocks this week will give me some badly needed down time between times spent at the hospital with DH.
