The idea came from some of my earlier knitting experiments and one very lumpy hat. With the invention of less flammable light sources (like LEDs) lamps can wear sweaters without burning up. So I decided to find out what a topographic textile looks like in the context of lighting.
Textured felt can be a very interesting material to shine light through. Thickness is pretty consistent, so translucency is actually determined by proximity to the light source. The peaks are dark, while the valleys show more radiant light.
The result is a luminescent pineapple - a very squishy and fuzzy luminescent pineapple.
