The Fun Theory

People are crossing the streets and ignoring the traffic lights every day. Why? Maybe they don't have much time, they don't care or they just don't want to wait. Probably because it's no fun to wait. But what if there is a fun way to wait? This is where the "concert-traffic-light" comes in. In front of a traffic light there is a floor sticker with electrical sensors underneath. Each sensor stands for a position in an orchestra, e.g. a violin. By standing on one sensor this particular instrument begins to play.

In cities we encounter the problem of drivers not stopping at pedestrian crossings if there's no red light. This idea will prove that encouraging drivers with a little fun test results for the better and many more will stop. The idea is very simple: drivers are encouraged to guess the right weight of the pedestrians that are waiting to cross the street. When a pedestrian is waiting to cross, a big sign could be read by the drivers. This will say: Guess the Right Weight. The driver will stop to see if he/she can guess the weight of the pedestrian or pedestrians that are about to cross.

Recycling is getting more and more wide-spread. We will have learnt already how things are possible to be reused, how they should be sorted and where they should be put. However, more attention should still be paid to the recycling of batteries. We all use appliances for which batteries are needed. But when the batteries run down, what do we do with them? Sometimes we take them and throw them away in a box or a bin somewhere in an electric appliance shop. Why not playing a bit when throwing them away, though? All of us have once played Tetris, so why not playing it with run down batteries?

My proposal for the problem of abandoned and broken glass in public places of meeting is inspired to Bruno Munari's projected painting and at the same time to a popular game of our childhood: the kaleidoscope. So, throwing the glass bottles in a special container made of a "glass crusher" and of a suitable projector, we can create several compositions subsequently. A downright "open work" in continuous transformation thanks especially to the people - often young people - that won't be anymore "only" responsible citizens not polluting, but also active part and creators of pictorial works.

A guillotine, if one designed to crush rather than cut. The weight of the crusher will need to be pretty significant, so the motive force to elevate it is a geared ratchet (cool sound) powered by pedaling a bicycle. One at the drop point, a can (or collection) is placed underneath to be flattened. Once so squished, a trapdoor can be activated to drop them into the receptacle below.

Your kid got tired of that old toy and keep asking you to buy something different. To encourage them to exchange the old for a different one, just take them to the Magic BoXchange and they will learn that an old thing can be recycled. All they have to do is to insert the old toy inside the box, wait a little bit, and surprise: a different toy will show up on the other side of the machine. You can choose between boys and girls toys', and if they are not satisfied they can keep on exchanging it. Submitted by Silvia Noronha.

Uses a big Perspex dome with a long tube built into a slider leading from a side easy insertion level to a point just over cone leading to the base centre. Like a telescope observatory. At base centre in interior an old wood chipper motor/blade or shredder, geared to be connected to a cycle-powered input. You 'load' PEP bottles into the tube. You then slide it upright (using screwed in 330ml bottle handles) to drop into the cone.

There is a trash lays on the ground. If someone picks it up. There will be spot light lighting on that person, the sound of applaud arise, and a microphone comes down from above. So that person can thank his/her parents who educated him/her so well. The point is to create a new experience of pleasure from a bad experience. So next time, when that person ever sees a trash on the ground, will reminds him/her this fun experience. Submitted by Elim Cheng.

I want to arise the awareness of the fact that everyone needs to feel they've been needed, and it's ok to admit we're needy sometimes. To do that, I made two "needy objects", they need the owner's attentions to make them work. One is an alarm clock, to stop the alarm, the owner needs to hug it. The other one is a speaker, the volume will go crazy when the owner is not around. The owner needs to pet it to make it calm down. To see more: http://ineedyoutoneedme.com. Submitted by Elim Cheng.
