MAIN PURPOSE: Flip a cascade of photos with one tilt
A Jacob's ladder for photos: six framed tiles joined by ribbon lattice so that tipping the top tile makes the next seem to cascade down the chain, flipping each picture over. Glue three 10 mm ribbons per joint, alternating sides; the recess holds a 66 x 91 mm print.

MAIN PURPOSE: Stand a place card or photo in a stone fissure
A place card holder modelled on lithops, the living stones of southern Africa: two fleshy lobes split by a fissure where new leaves grow. The fissure is the slot, so each guest card appears to sprout from the stone, and the open lobes take a few pebbles for weight or a sugared almond for each guest.

MAIN PURPOSE: Hold an avocado stone over water to sprout
A collar for growing an avocado from its stone without toothpicks. Rest the ring on any glass 70 to 85 mm across, press the stone into the centre pointed end up and the three tongues grip it with its base in the water. The slit lets the ring flex as the stone splits and the root grows.

MAIN PURPOSE: Stand a 3 mm fan, sign or plate upright
The foot for the Gorgonia fan, after a kelp holdfast, the clutch of branching rootlets that anchors kelp against waves. Seven forked haptera spread to a 112 mm footprint, and the slot from one side to past the centre grips any 3 mm plate upright: the sea fan, an acrylic sign or a printed name plate.

MAIN PURPOSE: Show autorotation with a printed maple seed
A flying maple key. Press an M4 nut into the seed pocket, drop it from a stair or balcony and it autorotates like a sycamore seed, spinning down slowly on its single wing. Bend the trailing edge slightly to change its spin.

MAIN PURPOSE: Glide a printed seed wing across a room
A hand glider after the seed of the Javan cucumber, the swept crescent wing that inspired early tailless aircraft. Press an M4 nut into the nose pocket for balance, then launch it gently level from a height and it glides in long, slow swings across the room.

MAIN PURPOSE: Lift pet hair from sofas, car seats and beds
A pet hair remover that works like a burr. Burdock hooks catch fur and let go one way only; the edge of this rake is a row of small raked hooks, so a pull across the sofa gathers hair into a roll and a push releases it. Hang it by the hole in the handle.

MAIN PURPOSE: Gather plant stems round a cane without tying
A support for floppy stems that coils like a tendril. Slide the hub down a garden cane to the right height, then feed the stems of peonies, tomatoes or tall herbs into the open end of the spiral and slide them round into its turns. Nothing needs tying, and each stem keeps its own channel.

MAIN PURPOSE: Play a pair of seed pod castanets
Castanets from a seed pod. Jacaranda pods are round woody shells that children clack together; print two of these cupped valves, tie them through the stalk holes with cord so the rims face each other, loop the cord over your thumb and snap them with your fingers.

MAIN PURPOSE: Make a vibration-powered walking toy
A bristlebot that walks like a grass seed. A wild oat awn has stiff backward barbs, so every shake ratchets the seed forward; this body stands on eight raked legs, and a coin vibration motor with a CR2032 in its hollow back makes it scurry across the table.
