These are the digitalised leftovers of one of my latest fun projects (two weeks ago):

Materials
Body: pan-fried aubergine
Bridge: raw chillies (not too sharp or you will have intonation problems)
Strings: zucchini strips (sauté), stretched with Photoshop
Neck: with Photoshop cut out ukulele neck
Glue: Photoshop
Varnish: unsharp mask in Photoshop
Sound sample: miam! (non edible neck & tuners)
Lifespan of the instrument: ca. 20 minutes
