This is also part of a Miley Cyrus "I Want to Be Your Friend" gift package project.

🎁 Burning Man Gift Concept: "Nothing Compares 2 U" Audible Fridge Gift

• Concept: Rather than capturing a photo, participants capture a 10-second audible memory with a friend. Press record, speak your truth, play it back. Magnetic, hangable, and touchable.

• Power: 3V coin cell should be enough for short messages. If it’s not holding charge well under load, consider a small Li-ion 3.7V cell (like 102030).

• Aesthetic: Decorate with feathers, glitter, laser-cut silhouettes, or a heart-shaped paper tag saying “Nothing Compares 2 U”.

💰 Angel Donor Breakdown for 500 Units

→ Total: $1,850–$2,850 (sometimes you can get things in kits that include some line items)
A ~$2K angel donor could make it happen at scale. Even more if assembly gets community help.
