The full set built so far is about 35 individual tiles. I will aim to design and build a few more just to cut down on the repetition with the finish piece. I can now start to see how the tiles can be group in sets of 4 (where I have built mirrored tiles) and I can see how the curved tiles can be arranged in a range of layouts for interest.
The shadows from the sunlight today are great and hopefully, the layout when finished in the correct lighting will have the give the same effect.
