I thought that I would go abstract today with an IPhone image (Figure 1) taken through the bullseye of a crown glass window.

Bullseye glass was an early type (first developed in 14th century France)  or process of making window glass, where the glass was first blown into a “crown” or hollow globe. It was then transferred from the blowpipe and then flattened by centrifugal force. The globe was spun out until it was a flat disk, which could be up to six feet in diameter.

The obvious point was that the thick center portion was the least expensive. But from an artistic abstract point of view it creates the most desirable distortions.

Also, if I may make a request tonight (July 19th, 2016) HatiandSkoll is undergoing a server transfer. For about four hours we may lose location fidelity with our name server. That means that the address may not work. If this continues beyond Tuesday morning Eastern Time, could you please let me know. Thanks so much, David
