Animated components

Hi all,
I'd like to know if someone have already tried to implement animation on ui components ? For example subwindows or calendar popup of the date selection with growing effects like the last popupview, or a sliding effect in accordions, horizontal subwindow moving (to hide side panel). Another idea could be transitions while replacing a pane by another (for use in multiview).
Hope my question is not offtopic
Thx

It's not as flexible as your examples, but very nice and easy to use nonetheless.

Wow, thx a lot, exactly what i need. i'll wait 6.3 taped out... still 11 long days :grin:

Nightly builds are there already :)
