Flicker might be reduceable, but at the expense of ...

Here is the final Butterfly version, featuring six flyoing insects. UNZIP, LRUN or ESCape, (P)ause or (R)eplay. Tested ok on QPC2.

Now everything works ok, will allow other varied future animations, all done with very liitle DATA, via morphing. Steve.

Hi,

Multiple, multi-directional butterflies now tested ok on QPC2. Speed is no problem with many flying simultaneously... Steve.
