This is where the Replicate too needs a tiny extension, to rotate as well as lay out irregular shaped bricks. I did think of doing something like this method but did not bother as I know it would have taken ages to get everything to the right dimensions, angle and precise contiguity.

Thanks, I enjoy doing them and have been given a modest honorary commission to illustrate a 400,000 person database of people and their relations. Sounds like I'll be in my grave first. And since the interest is obviously so great, here's the Gobony border and a shield using same. Apologies for the goggles on the lions but they were the best I could find. <http://powys.org/riscos/Gobony.zip> -- Tim Powys-Lybbe tim@xxxxxxxxx for a miscellany of bygones: http://powys.org/ ------------------------------------------------------------ To change, suspend or cancel your subscription go to //www.freelists.org/list/artworks ------------------------------------------------------------
