Be an electronic Georges Seurat!
The Pointillisted app generates pointillist artwork using images from the Photo Library, including those shared in iCloud, similar to the photo mosaic generating app Patched.
Generated images can be customized by size and type of point (rectangle, circle, triangle, and hexagon), size adjusted to color, and variance in location. Single colors can be isolated in an image. Save artwork to the Photo Library and share through standard services: copying to the pasteboard, posting to social media sites, and sending via email or SMS.
To turn pointillist artwork into a sticky note mosaic, download the sister app, Posted.
