Useful. Threadless get closer with this:
Books have the ISBN. Tshirts should have a ISTN. A standardised system for organising tshirt designs. It would make tshirt searching so much easier. I propose a 4 part system limited to 16 characters.TGEK-BINP-MBAA-XL
producer - design - item - size
thinkgeek - binary people - mens black - extra large
The first and last sections are standardised. So you always know where it was bought and what size it was. The central two parts are self managed by the producer. They get to name the design, and use whatever code suits them for the item.
One spin off I can foresee is a subtle sleeve or back of neck print of the producer code on the shirt. So that when I see a shirt on the street I can just glance at the sleeve and note "right, he got that shirt from GYOI! - must check them out". Benefits the shop, benefits me in finding a new shirt, clutters up my sleeve a little.
Some central area, nothing more complicated than a wiki, could allow producers to claim a producer code and then optionally maintain a list of design codes on that site. This would have promotional advantages, and would help them to show they were first with a design when they get ripped off on cafepress forty times.
Adding structure to the chaotic world of t-shirts. Hardly an earth shattering global innovation, but would be cool. Comment if you want to reserve a cool 4 letter acronym!
The sketch (May I apologise for the quality of photography. I seriously need a new flash!)
What if I could tune this problematic guttering to spray that overflow water into fancy patterns, swirling fountains, or clean jets aimed at a pond in the garden? What if I could have four pools, graded to the weather, and four separate spouts fed them? What if I could use this to state how heavy the rain was? "Look dear, it's dinging down a 3er out there". An end piece for a standard gutter should be formable from copper to direct overflow in this way. The pools could look great - every garden benefits from a pool or two. We're not talking mammoth lakes here, just little foot or two across garden ponds. I guess any newts that took residence in the big pool might get a shock during a 'grade four downpour' when the jet turns on - bet hey - they can swim. I'd pay for that. Some artisan gutterer turns up at my house with his copper bending kit, his intuition, and an apprentice to dig a few ponds in 'just the right place'. Think how cool your neighbours would think you were. "look John, next doors house looks so PRETTY when it rains!"
This would really fit with my liking for arbitrary measurement. When making coffee we talk about a '3 spooner' or a '4 spooner'. When we recently got all new cutlery the meaning of 'spoon' changed. Our terminology didn't. It just feels more organic. I like the thought that a 'pool 2 day' at my house is a 'pool 4' half a mile away. Personal units of measurement are so much more touchy feely than metric units.
Taking this a step further, an RFID in your cup would track your personal consumption if you shared a cafetiere. If you had two cups you could have a Coffee and a Green Tea cup. Try to keep them in balance! "turn it into a game" as Seymour would say. You are reaching for the kettle and suddenly "I'm sorry dave, green tea this time". The company could milk the cash by offering smaller cups - which count less. If you were allowed 2 mugs a day, that could be 4 cups, or 6 minicups. They could sell you a mug, then when you drink more than 2 a day along with the "I'm sorry Dave..." message could suggest you buy a smaller cup. Another revenue earner could be a SMS reply to the "Sorry Dave..." message saying "I'm having a decaff" or "I spilled it - honest" to lower your daily count. (btw did you know the caff from decaff goes into soft drinks - I never thought about where soft drink caffeine came from) I like my current coffee cup though, so they would have to sell an add on monitor. This would actually look quite cool as a big tag for the handle - like when things in supermarkets are tagged with huge lumps of plastic to set off the alarms. A public symbol of your dependency. And they'd have to be dishwasher safe. A sophisticated mini sticker for underneath the cup would also work - more subtle. And of course the league table of coffee drinkers could allow caffeine heads to show off their intake. "Dude I had like 3 mugs and 7 espresso cups this morning". Blog chicklets to let you post your current daily and weekly count would promote the site.
