1) PopForward Gravity Shelf — the shelf that presents your stuff when you open the door

Why it’s mind-blowing: open the cabinet and the shelf tilts forward a little so the items slide into perfect view — like the cabinet is handing you the thing you wanted. Tiny mechanical elegance = huge visual payoff.
Materials (cheap / tiny): thin plywood or plastic sheet (shelf), two small piano hinges, a short torsion spring or elastic band, two tiny guide pins (dowel pegs), 4 small screws, felt pads.
Build steps (fast):

1. Cut shelf to size and mount two small piano hinges on the back edge inside the cabinet so shelf can tilt forward.
2. Install two guide pegs near the front corners that limit forward tilt to ~15–25°.
3. Add a tiny torsion spring or concealed elastic band between the cabinet rear and shelf underside so when door closes the shelf snaps back flat; when door opens the spring lets it tilt forward smoothly.
4. Add felt pads on front lip so items stop neatly and don’t slide off.
   How to demo (7-second reveal): closed cabinet → open door → shelf tilts, items slide to front, user grabs mug/snack without rummaging — overlay: “It just presents itself.”

2) Tap-Tone Finder Tags — give every item its own musical fingerprint

Why it’s mind-blowing: attach a tiny tuned resonator tag to keys, chargers, remotes — tap the pile and each tag gives a unique musical pitch so you can instantly identify the missing item by tone. No electronics required — it’s acoustic magic.
Materials: tiny metal disks (brass washers or shim), short rubber grommet (mount), thin plastic tag, permanent marker (for visual ID), superglue. Optional: small straw resonators for more distinct tones.
Build steps (fast):

1. Cut small plastic tags and glue a tuned metal disk to each (different disk sizes or small cuts change pitch).
2. Attach tags to items with a micro-loop or adhesive pad.
3. To catalog, tap each tagged item and record a 1-second note (use phone voice memo) labeled with the item name.
4. When searching, tap the pile or drawer and match the sound by ear or play recorded reference for a quick A/B.
   How to demo (7-second reveal): messy drawer → you tap each tag quickly → friendly jingle of distinct notes → you point to correct charger instantly — overlay: “Find by sound, not sight.”

3) CascadeStack Pull Boxes — stacked boxes that open in a dramatic cascade with one pull

Why it’s mind-blowing: stacked storage that cascades open like falling dominoes on a tiny controlled hinge system — pull the front handle once and the whole stack fans out so every compartment is accessible at once. Satisfying, cinematic, extremely useful for small drawers, craft supplies, or pantry jars.
Materials: 3–5 thin shallow boxes (plastic or wood), small piano/hook hinges, 1 slim braided cord, two micro pulleys (or smooth eyelets), tiny screws, rubber stop.
Build steps (fast):

1. Stack boxes with hinges linking each box’s back edge to the next box’s bottom back (so pulling one tilts the next).
2. Run a thin cord through micro eyelets along the back of the stack; the cord attaches to the front lip of the top (outermost) box. The cord tension governs the cascade speed.
3. Add a small rubber stop so boxes cascade to a controlled angle and don’t flop open.
4. Mount the stack in drawer or on countertop. A single forward pull on the front handle causes box #1 to tilt, the cord transfers motion and each successive box fans out neatly.
   How to demo (7-second reveal): neutral shot of closed stack → quick tug → boxes cascade open in a smooth fan exposing organized contents — overlay: “One pull, everything visible.”

Quick usage notes

• All three are low-tech, easy to prototype with basic tools.
• Design for smooth, damped motion (felt pads / rubber stops) so the visuals are clean and satisfying.
• These are safe for household use; keep small parts away from children.
