How To make A Plant Move?

How To make A Plant Move?
I made this plant with curves. but how can I animate them?
I dont want to make a mesh (Alt+c) and juse shape key’s. I know how I can do that (the Essential Blender). I’m looking for a way to animate the actual curves.
Can someone explain how I can do this?

Go into edit mode, select a point on the curve and press alt+h and animate the resulting empty.

oké, It works! but not with Alt+h but Ctrl+h and than add empty.
mybe a diverend version? I juse 2.44.
anyway Thanks! i got it now.

Seriously, you should upgrade.

I am sorry, it is control-H.

Yes, I Know But 2.44 works best with Mancandy :o

get mancandy 2.3 optimized for 2.46
