Nice simple graphics. I have a few to upload later.

Brilliant shapes and color.

Excellent work.

Lovely lines and colour.

Terrific lines and zippy colours … there is a group ‘art in math’ that this would fit in perfectly! http://www.redbubble.com/groups/art-in-math

excellent capture

Love those colours, and the lines, and the composition. ; )

Great lines and colors! You have a really good eye for this kind of image. :)

Like your composed design here also…and impressive for an iphone…another fave. >Ron<
