...where science and art meet...
The planar crystallographic groups (also called wallpaper groups) are a fascinating topic on the borderline of science and art. Each infinite regular Ornament that has specific symmetry properties defined by its mirror axes, rotation centers and glide reflections belongs to one of the wallpaper groups. Amazingly, there are only 17 different possibilities in which these elementary symmetries can be combined to form a planar Ornament. iOrnament is an app that lets you create creative and artistic ornaments and that also provides backgrounds that explain what is actually going on.

On the one hand iOrnament is a drawing app. You draw simple strokes with your finger or a stylus - iOrnament repeats them automatically according to the rules of a selected symmetry group. By just drawing a few strokes fascinating patterns emerge. Experience shows that people of almost all ages starting from 3 year old kids up to scientifically or artistically interested grownups can spend hours in the creative process of creating ornaments, tilings or infinite knots. iOrnament provides a very flexible palette of colors and pens to let you express your artistic ideas.

Scientific backgrounds:
Behind the structure of ornaments there is a vast amount of theory that gives answers to questions like "How does one symmetry imply another one?", "Which planar symmetries can be used to create ornaments?", "Why are there exactly 17 principal classes of ornaments?". Questions like this are treated in an interactive pop-up book that comes with iOrnament. Each topic comes with an interactive explanation that allows to perform your own experiments in order to get intuition and a deeper understanding.

An interactive gallery on this site gives an impression of the diversity of different patterns that can be created with iOrnament. Flourish designs, highly geometric tilings, intricate weavings or infinite knots are equally accessible. Drawing an interesting ornament is a Zen like process. Often while you draw an ornament interesting structures emerge that can be used to create designs you never dreamed of.
