...but what it does aint much. The app store is replete with similar psychedelic image-generation toys. I imagine it is the ease with which such trippy images can be manipulated with touch on the iPad that has really allowed the genre to blossom. There is little to benchmark these apps against but other apps doing similar things. In that regard, Geom-e-tree gives you control over a couple parameters of a tree-like fractal, allowing you to change the orientation, and grow or shrink the complexity. However, as the complexity grows, lag becomes crippling. Playing around with it, youll figure out where those limits are and simply learn to stay away from them, usually. There are also a number of theme selections to change the visual appearance of your "tree", but sadly no option to customize beyond that choice. Among this type of app, there runs a spectrum between the freedom to manipulate and ease-of-use. Geom-e-tree is easy to pick up and play around with, but you may find yourself running out of new ways to play with it. Like most of this type of app, Geom-e-tree is inexpensive, so if the images in the screenshots are especially appealing to you, why not take it for a spin? Look up Artree while youre at it, for a different approach to the trippy-tree that lets you smooth trace a line that will sprout up to your specifications.
