Pineapple : 

Ripened to yellow-gold,

Pointy fellow,

Interesting pattern ... 

Did origami prototyping. 

pattern : water bom 

Will investigate the possibility of using waffle pattern. 

First I designed algorithm using grass hoper and then calculated the joints using rhino ( a 3D modeling tool ). Then printed out the 1/5 size model using laser cutter

Since its a lamp shade, the material has to be soft and safe even when it is falling down. Also it needs to be beautiful as a lamp. Therefore I found a thinner, clearer material which is tracing paper. Bought it at TAKEO. 

44*88cm Kurashiko Trasing Paper

The inside resembles the shape of cut pineapples. 

I used MDF for the material because it's has low risk of catching fire. I made sure to leave some space from the light to release the heat.

My first prototype made a gap between the lights so I made slight adjustments.
