I can see them too... butterflies and flaming bats. This is a really cool design, though a little challenging on the eyes after a bit. Looks like one of those "magic eye" designs. Nice work!

Eye popping colors on these "butterflies" which are very easy to spot now that you've put it together. I put this up on my desktop and realized that my icons had disappeared..lol..but at a lower resolution I could arrange my icons around the border. It would certainly keep a person awake at the office :) I also looked through your gallery to see what other work you've done, and I found this to be a nice departure from you usual, good work. So I have to commend you on daring to try something a little different. Your color choices are very well coordinated and create a very pleasing combination. What program did you use to make this? Nice post. :)PJ

It is very interesting but it hurts my eyes if I stare too long! The color combinations are captvating.

Looks like an afghan pattern I tried unsuccessfully to do a few years ago!

Interesting! It looks like the work of M.C. Escher (http://www.mcescher.nl/)...
