Have a simple 3D scan of your head fashioned into a sliced pan
Instead of a complete photo-booth, there is only a large enough
booth into which you insert your head, for long enough to enable
3D scan to take place.
This provides the file that's translated into a simple two part
created using a 3D printer. Various types of filling for the mould
then offered, starting with basic white or brown bread options.
With a small amount of digital intrusion, the mould can be altered to cause the bread's crust to be custom positioned to fall on the hair/beard/eyebrow areas.
The completed loaf is baked and delivered sliced or unsliced in a
nicely printed cake type box. (along with the original mould) Once the file is stored, additional options can be ordered, like cup cake baking trays or ice cube makers, all replicating the features of your 3D head.
You can use the bread to make sandwiches or skewer it on a spike
a public place and enjoy the birds picking away at it.
