Sustainable Aehsthetics' . . . for me it means to create something new from already existing things. This can be something useful in the household, clothes, decorative objects or something that helps with research. In my opinion, it also depends on how you deal with the resources you use for your project, i. e. being able to estimate the amount and not use everything in excess. Perhaps you could also say that you can make a lot out of a little. With Sustainable Aehsthetics, I also think of variability, that is to try out a lot and venture into projects that you have always been interested in or that you have never done before. In my case, this would be woodworking or modelling with damp clay.
Ideas
Loudspeaker
My idea is to make a small decorative house, which is made of wood. In terms of sustainability, I try to make sure that the wood I want to use is not very expensive. An additional consideration is to equip the house with LED lights or a speaker. For the lights, the idea is to light the small house from the inside. For the LED's I would take an old string of lights or purchase an LED light with cables on the internet. The idea with the speaker would be that I would install it so that it is not visible. The final product should then be able to play music or christmas sounds. In the end, my product should be built so that it lasts a few years, because that is another point of sustainability for me.
