A handy variation on the "enum",

The imageEnum Contraption:

Load this contraption with a selection of images, and then pick between them. Exposes attributes "value" (an Image interface, read-only!), "imageIndex" (an integer, read/write), respects the standard "show" and "locked" attributes, and provides a "change[]" event, just like enums and the slider.

is there a way to have a kind of loop, so that when you click on the right arrow when you're at the last text, it goes back to the first text, and vice versa?
