Identiconizer!

This is a port of ChameleonOS' contact identicons feature (available in the JellyBean versions) with some additional features and fixes. When enabled, new contacts will be assigned a unique identicon instead of the default picture.

Features:

• Use identicons for newly created contacts. A service is normally used to detect new contacts. If you use the Xposed Framework, you can enable Identiconizer! as a module instead to integrate the application into the system.
• Choose from five different identicon styles: Retro, Contemporary, Spirograph, Dot Matrix and Gmail.
• Specify the identicon sizes, from 96x96 up to 720x720 (256x256 max on ICS.)
• Choose a custom background color for the created identicons.
• Create identicons for all contacts without a photo in one go.
• Remove identicons from all contacts that have one set.
• Contacts list to add/remove Identicon to/from wanted contacts only.
