About This Design

Earth And Venus Per Martineau (cards) Card

Earth And Venus Per Martineau (cards) Card

This image was inspired by the remarkable work of John Martineau, in "A Little Book of Coincidence". Five tiled spiral galactic (NGC300) planes form the background. The perigee and apogee relationship between Earth and Venus is described by a nested pentagram pair. The orbit of Venus is represented by the larger sphere (with the Sun in its centre), and smaller sphere has the Earth at its centre. The five inner spheres just fit inside the outer circle to touch the inner sphere. The radius ratio of outer circle to smaller circle is phi ** 4. Spheres are used to represent the circles for artistic effect, and the outermost five spheres are decorative only. More info: http://www.GeometryCode.com. I think John Martineau's name will (some day, hopefully soon!) be heralded among Kepler, Galileo, Newton and Einstein for the astronomical discoveries he's made. Here's a link to John's book if you haven't seen it (HIGHLY recommended): http://www.amazon.com/exec/obidos/ASIN/0802713882/intent-20 (Created with POV-Ray http://www.povray.org)

Folded Greeting Card, Size: Standard, 5" x 7", Paper: Signature Matte, Envelopes: White
Really pleased with the card quality. The perfect theme to personalize a birthday celebration. Birthday greeting combined with a Christmas wish for my nieces Christmas Birthday. Perfect! These colours really pop on this Matte finish. The cute funny monkey expressions add humour to a birthday card surprise.

This card is beautiful. I loved that I could pick special poems that mean something to me and will mean so much to my friend who lost her pet soul mate. The picture and the poems I requested turned out Purrfect! I will definitely be back to place more orders with this seller. Thank you for the amazing work you do!!
