       | If you want to play with any of these lens descriptions (or look
       | at code for simulating them), I made a free and open source
       | visual web UI for lens design. The default project when you visit
       | it is a double gauss lens similar to the one shown in the
       | article.

         | often self-explanatory. I like it.

           | scratch. The general concept of a spreadsheet-like data
           | editor next to a visual view is a standard paradigm in
           | commercial lens design software like Quadoa/OSLO/CODE V.

       | I always wanted to play with Optica for Mathematica. It seems
       | like a problem that would lend itself really well to the Wolfram
       | way of visual + functional programming. However I've never met
       | anyone who uses it and while academics usually get Mathematica
       | for free, the plugin is pricey.

       | related keywords. If anyone has it please share :-)
