Create Patterns From Images: Repper
Repper is a free web-based application for creating patterns from any image.
It is possible to upload a custom image or use a random image that Repper provides to start using the application.
At this point, the only thing to do is to start dragging a resizable box where it displays the generated pattern instantly.
The created patterns can be saved or downloaded. And, the saved ones can be browsed by other users.
While browsing the gallery, you can vote patterns & sort them according to their popularity, view numbers, etc.
