Picture of Makey Makey Piano
I built a Makey Makey Veggie Piano to bring to the "Believe In People Summer Celebration" Music Festival at Woodwynn Farms on Vancouver Island in BC, Canada (a short drive from Victoria, the capital city of BC). The farm focuses on helping homeless people develop work skills and self respect, along with a deep understanding of sustainability and community living, with a goal of reintegration into society.

The Makey Makey Veggie Piano fit the musical theme and the goal was to have fun and make people smile. Success!

This project took me about 10 hours.

Tools and parts required:

Makey Makey
USB cable, and alligator clips (comes with Makey Makey)
Computer running Windows, MAC or Linux
VMPK Piano software
VMPK keymap file - Attached to this step - "Makey Makey 18 Key Veg.xml"
Makey Makey Arduino program
Acrylic or wood to mount your piano parts to
Ruler or straight edge
Exacto knife or box cutter
Hinges (optional)
Bolts and Nuts
Glue (optional)
22 AWG solid core wire
Wire cutters
Wire strippers
Antistatic wrist strap or velcro cable strap (if you are using a Velcro cable strap you will also need tin foil and scissors)
Painters tape
Solder and soldering gun
Soldering flux
Heat shrink
Finishing nails
Drill &1/4" drill bit
Loud computer speakers
20 vegetables + a few extra - I used carrots and green/yellow zucchinis 
Arduino Software (PLEASE use Linux to program the Makey Makey; Windows requires drivers, which means going into the hardware manager and updating the drivers before it updates itself while trying to upload to the Makey Makey... believe me when I say that using Linux is much easier!)
And don't forget your Instructables sticker ;)
