With mollex we have extracted the snail shells from the photos of the "Museum für Naturkunde Berlin" and generated new pictures. SnailSnap is now an extension, so that you can take a selfie of yourself and create a mosaic of snail shells. By tapping on the snail shell you can see meta information about the snails.
some params should be available to be manipulated through a ui, e.g. the level of details. this should at least be implemented for debugging purposes.
