You have written a very nice description in your first comment - perhaps you should copy that paragraph to the description of the set itself. As comments are added to this page, the older ones disappear, but the set description is always visible.
Also, do not add cursors-set to the identifier of your future sets (I have removed it from your current sets, which is bad, because the urls have now changed and now I must remove twitter and facebook entries due to broken links) - if you are not sure, just leave the Identifier field empty and give the set a good name and all will be fine. ...and only add relevant tags (2-3 max) - less is better - they only serve for connecting sets and having irrelevant tags on your set will cause confusion (again, I have fixed the tags for you).
And... the animations are great!.
