I downloaded it late last week and I must say, I found it to be pretty user friendly.....here is a look at a few of my drawings, keeping in mind, with this app, I need only draw one portion of the design, the app repeats each stroke for me as I go along. Guess I can put away my mirrors that I have used for so long to create symmetrical design.
these are just examples where I am creating Kaleidoscopic type images, this app allows you to do so much more.
I found lots of videos showing the app in use... but not much in the way of a basic tutorial showing what to expect....the tools, options, how to make copies, save, export and all that sort of thing.....so...I made one. I have only touched on the basics to get one started, there is much more to explore....and yes...for those who love to play with colour, you can pull up a pallet, mix colours, add colour with varying degrees of opacity, and well....if you have an iPad and like to experiment with design....you just may want to give this a look. But don't say I did not warn you....it is addictive!
here is a link to the video tutorial I made....it is not slick, but it will certainly help get you started if you are unfamiliar with this sort of program
