Creating an animation demonstrating astronomical parallax in IDL

Posted originally in this blog post in 2012, updated in 2014. Re-discovered and code made open in 2018.

Requires:

• IDL (used version 7.0, newer probably works) to render the images as .eps files
• ImageMagick to convert from IDL's normal .eps files to single .gif files
• gifsicle to render .gif images into an animated GIF

Note: Now I would do this via Python, but I would probably render it still using gifsicle...
