Although the tinsel is a distinctive element in the holidays, due to the computational difficulty of the simulation does not appear too often in the wallpapers that I leave on the blog.
It is necessary to simulate many thousands of tiny hairs that reflect light between them in a dance almost infinite rays to get a more or less acceptable appearance.
In the following wallpaper, after modelar espumillón en Blender, We added a couple of fields and a particle system generating a shower of stars to complete the stage.
To get an idea of the difficulty of this technique, the image in high resolution (HD) has been slow to generate one hours, 15 minutes 10 seconds 200 past (samples) Calculation.
A wallpaper with silver tones to Christmas tinsel and bright colors in the stars, you can get in resolution 1280 x 1080 click on the image.
