Here's a tip on a secret way to get a listing of all current BioInteractive resource pages. This used to be a page that only BioInteractive staff used, but we had enough requests for a similar listing that we're (slowly) opening it up to the public.
Go to the following URL: http://www.hhmi.org/biointeractive-urls
You can sort this list alphabetically, or by date posted. If you need a different type of sorting, or want to limit it to just (say) animations, if you scroll all the way to the bottom left hand corner, you will see a tiny "CSV" button. This will download a CSV ("comma-separated values") text document that you can bring into your spreadsheet of choice for further manipulations.
Let us know if this tip helps!
