Day 47. These pretty mandala designs were made with an iPad app called iOrnament. It lets you create symmetrical patterns with amazing sophistication, especially if you splurge out for the 99c in-app purchase to unlock the extra features. I created one basic round mandala design then applied some randomising effects to it, to create the four variations you see here. All four of these design variations are based the same basic pattern.
Once I made all four of them I arranged them in this 4-up grid design using another app called Diptic, which can arrange multiple images in a single framed picture.
