Did you just re-made that? Impressive!
I’ve heard about Aviary Peacock before, but it seems that I should have a look at it again.
The funny thing is that I was checking out your latest incubator projects like an hour ago.
Yes, I just re-made it which took honestly took just something like 4 minutes. Well – obviously I know my own tool, which is admittedly not the easiest to understand if you open it the first time. But I encourage you to open the composition and play with it yourself (which is what Peacock is about).
The open source vector graphics editor Inkscape (similar to Illustrator) can do this too… it’s called cloning, outputs vector graphics (svg) and exports to png etc. It’s available here: http://www.inkscape.org/
But it’s of course not only about the tools you know.
