The fancytooltips package has been inspired by cooltooltips
package. In contrast to cooltooltips, fancytooltips allows to
include tooltips which contain arbitrary TeX material or a series of
TeX materials (aminated graphics) from an external PDF file. The demo
files example.pdf and example-min.pdf. To see the tooltips, you have
to open these files in Adobe Reader. The links and JavaScripts are
inserted using eforms.sty package from acroTeX bundle. The TeX file 
can be processed by pdflatex or latex + dvips + distiller + Adobe 
Acrobat.
