Preview of Break-glass emergency chocolate box
By Krypto
Complexity
Simple
MAIN PURPOSE: Keep a chocolate bar behind "glass" for genuine desk emergencies
IN CASE OF EMERGENCY, BREAK GLASS. Mount it by the desk with a chocolate bar (or a spare phone charger, or headache tablets) displayed behind the window. The "glass" is a sheet of clear plastic that slides in behind the front, so in a real emergency, such as a Monday, a deadline or a meeting that should have been an email, you just lift it out. A great gift for anyone who has ever said "I need chocolate".

Preview of Jastrow illusion twin trays
By Krypto
Complexity
Medium
MAIN PURPOSE: Hold pens in two identical curved trays that seem to change size when swapped
These two curved desk trays are exactly the same size, but nobody will believe it. Laid one above the other, the lower one looks clearly bigger. Swap them over and the other one grows. It is the Jastrow illusion, found in 1889: your eye compares the short inner edge of the top curve with the long outer edge of the one below. Use them for pens and clips, and keep a ruler handy for the arguments.

Preview of Fibonacci golden-rectangle desk tray
By Krypto
Complexity
Advanced
MAIN PURPOSE: Sort desk things into squares that grow by the Fibonacci sequence
A desk tray built from the Fibonacci sequence: squares of 8, 5, 3, 2, 1 and 1 units spiral inward and fit exactly into a golden rectangle, the proportion of the Parthenon and the nautilus shell. The big square takes a notebook, the next a phone, then a stack of sticky notes, then cards, and the two tiny squares hold SIM pins and memory cards. Each bay has its number engraved in the floor, so the spiral reads as you clear it.

Preview of Meshing gear-train desk caddy
By Krypto
Complexity
Advanced
MAIN PURPOSE: Sort desk tools into three gear-shaped pots whose teeth really mesh
Three proper spur gears, each with ten teeth, stand in a row with their teeth genuinely meshed, as if they were about to turn each other. The tall one holds pens, the middle one scissors and rulers, and the short one clips and erasers. It looks like a piece of a giant clock on the desk, and it makes a great gift for an engineer.

Preview of Tulou round-house organiser
By Krypto
Complexity
Simple
MAIN PURPOSE: Sort desk things into twelve rooms round a courtyard, like a Fujian tulou
The Hakka people of Fujian built tulou: round earth fortresses where a whole village lived in a ring of identical rooms facing a shared courtyard, with a single gate. This organiser is a little tulou for the desk. Twelve wedge-shaped rooms ring the round courtyard, which takes a cup or a plant, and an arched gate opens into the front room. Give every family member, colour or project its own room.

Preview of Levitating-pencil desk base
By Krypto
Complexity
Medium
MAIN PURPOSE: Float a pencil in mid-air on ring magnets, touching only a little end plate
A pencil that hangs in the air above the desk. Disc magnets pressed into the four sockets push up against two ring magnets slid onto the pencil, so it floats with nothing underneath it, held in line by its point resting lightly on the end plate. Flick it and it spins silently for a long time. Glue a coin or a small mirror on the end plate for the smoothest spin.

Preview of Floppy-disk desk tray
By Krypto
Complexity
Medium
MAIN PURPOSE: Sort desk bits in a giant 3.5-inch floppy disk
The save icon that outlived the thing it pictures, blown up into a desk tray. A shutter bay along the front takes pens, the big label area holds notes and cards, and 1.44 MB is engraved in the floor. A notched corner stands in for the write-protect tab. Anyone who remembers floppy disks will want one.

Preview of Jigsaw-piece link trays
By Krypto
Complexity
Simple (set)
MAIN PURPOSE: Print several puzzle-piece trays that lock together into one
A desk tray in the shape of a jigsaw piece, with two tabs and two blanks. Print four and they lock into a square, print nine and you have a 3x3 organiser, and pull one out to take it to another desk. It is a modular system that is also a puzzle.

Preview of Urchin pen hedge
By Krypto
Complexity
Advanced
MAIN PURPOSE: Stand pens upright in a sea-urchin dome
A pen holder based on a sea-urchin test. Eight pens stand apart in the pierced top so they never lean on each other, which makes it easy to grab the right one. The hollow body below keeps the tips off the desk.
