Now, this one impressed me lots. What you can see above is a picture of a rocket that I printed using “glow in the dark” fibre from Faberdashery. I took the picture using my Lumia 920 in pretty much pitch darkness. You can just see the edge of another, non-luminous, rocket on the left of the glowing one.
The picture was taken hand held and I’ve done nothing more to it than a slight crop. Amazing.
