Dear Mr. Fu-Kwun Hwang,
I have just subscribed for your forum. Thank you. I am looking for a suitable Java applet which can simulate gimbal movements. I need such a simulator to study the movement of HIV (the virus causing AIDS) when reaching close to the target cell (CD4+ T cell).  Some information on our research and personal details as well you can obtain visiting my site included  in my address at the bottom.
I have tried to find such Java software in your site and the links there but I failed. In this regard I would greatly appreciate if you be so kind as to create and provide me with such simulator. Please have some ideas of the design (actually the layout) at the links below.

Thanking you very much in advance I am,
Sincerely yours,
Evgeni Gabev.
