Hi All My first post on this mailing list. In reply to Ian Mckee's question, larger files can be rendered in Chaoscope - admittedly not very easily since the window you work in doesn't have zoom capability. I just create a new document at the required size, import the attractor file and then try to rotate the attractor the best I can till it looks correct - bearing in mind that depending on the size of document you've choosen, depends on just how much of the window you can physically see at any one time to enable you to position properly. This can take a while to get right, as basically your working blind....almost. Anyway below is a link to my version of Sous La Parabole (one of the programs example files) - it is 5000 x 3000 .JPG file zipped up. It doesn't look exactly the same as the original as I couldn't orient the attractor correctly. Be aware that this file is approx 7.7 MB in size - also there is no post work or resizing up in Photoshop at all - this is straight out of Chaoscope at the size you see. http://www.pixeldude.co.uk/renders/SousLaParabole.zip Let me know what you think....
