I really enjoy the idea of recursion -especially the technique of introducing elements into an image which can then be acted upon to change the image itself.

Today’s invention is a digital camera which has an extendable arm at the end of which some small, mutually-perpendicular spirit levels are attached.

To achieve an image with edges truly horizontal and vertical, the arm would be extended into the field of view and focussed upon.

The camera software would know where to look in the image to detect the spirit levels. It would then be able to lengthen or shorten two legs of the tripod, on which this system sits, pneumatically, via an electronically controlled pump/valve device.

The arm would be withdrawn, the scene refocussed and the picture taken.
