Mike thanks for the image -- tangent_void_800_5.jpg I like the blue background brightening to almost an electric blue -- which then nicely highlights the arms of the "foreground" pattern. The dark collections of "holes" in the background hint that there is something else hidden behind the blue background, too. - Hal Lane ######################## # hallane@earthlink.net ####################### -----Original Message----- From: Fractint [mailto:fractint-bounces@mailman.xmission.com] On Behalf Of Mike Frazier Sent: Monday, September 7, 2015 12:49 PM To: Fractint and General Fractals Discussion <fractint@mailman.xmission.com> Subject: [Fractint] Tangent Void This fractal mixes tangent and z^2.
