Some years ago a company called Fabrican invented  spray-on fabric in a can. Pressing the nozzle over your body releases ​a substance that resembles Silly String. It ​forms layers of textures that ​look like textiles. Now comes another innovative spray-on ​product called Volvo LifePaint.  Made by the Swedish automobile manufacturer Volvo, the spray releases a fine liquid that is invisible during the day yet reflects light​ at night.  By spraying on bicycles, clothes and other items, you add an extra layer of safety as you travel through the night.  The coating lasts a week and easily washes off.  I wonder if in collaborating with a company like Fabrican, they could develop colorful spray-on clothes that would become reflective by dusk.  The Volvo LifePaint is currently only available for purchase in London.
