-====== Sunshine Wallpaper ====== 
-Watching Danny Boyle'​s movie [[http://​en.wikipedia.org/​wiki/​Sunshine_%282007_film%29|Sunshine]] prompted me to attempt my own implementation of the solar observation room seen in the movie. My implementation uses live imagery from the [[http://​sdo.gsfc.nasa.gov/​|NASA Solar Dynamics Observatory]].

-Version 1 of my solar observatory is a bash script which uses wget and ImageMagick to download and combine together images of the sun at various wavelengths to produce a wallpaper image. If the script is triggered as a cron job, to execute every 10 minutes, the wallpaper will stay up-to-date. 
- 
-Install the script in a location where temporary files and the resultant file can be created.

-===== version 2 ===== 
-Version 2 will improve upon version 1 by using SDO imagery in the raw FITS format with contains 16-bits per channel intensity. This will provide a much greater dynamic range in the input data which I can use as a source for bloom and lens flare effects. 
- 
-I'm particular interested in making an implementation of this technique:
