Ahhh, have worked it out. Blue link not always shown unless you click on the http address. Lets now try an image...

It is quite difficult to find the artists on line that I viewed at the above exhibition. I also really liked a set of prints by Jose Delgado. They looked like pen and ink drawings but in fact I think they were lithographs. Here is an example of a similar piece of work. There was a lot of movement and simple variations in the marks made, fantastic!
Also, there were some etchings of the Seven Deadly Sins by Pieter Bruegal et Viejo. Again, I was fascinated by the various simple marks made that produced such intricate images. They are etchings made in 16th century.
Another fascinating image was Christoph Jamnitzer 'Old Man with Candle and Monsters', 1610. Fantastic patterns which looked like ammonites, formed the basis for the image.
Think the final artist that I will mention is Paul Klee, but will start this as a new entry as plenty to comment on.
