Fablab Barcelona students have made different designs for something big project. The projects include different furnitures, products and expermental designs.

The rotating accessory is LED connected to the cloth, which changes the color of the clothing and shows the temprature, the second is a footwear that will change its form by extending it to the upper and change the color as well.

Here are the project I proposed to be fabricated here in FabLab. The project is Lighting digital wearable designs which I thought I can go far with it.

For FabLab Addis- Here are some activities done in FabLab Bcn and We will be posting each activities done every Friday.

This is a self reproducing machine proposal
It condenses and distributes molecules in it by casting them inside. The inner and the outer shape is the same so that it duplicates it self. The proportion of distribution is a golden mean proportion which can be seen in plants and animals.
