Your probably going to have to eat the performance hit, but a time based
animation is simple. Change his y offset line to:

pth.AddString(s,ff,0,70,new Point(0,90*y+timeOffset*90),
StringFormat.GenericTypographic);

In this case timeOffset is a floating point number from 0.0 to 1.0... In
addition, you'll
want to change the loop to do a -1 to 5 instead of a 0 to 5... This'll handle
adding an
element below the bottom element as it begins to scroll up. As for scrolling a
huge region,
and not just editing his sample, I'll leave that up to you. You can't pre-blit
and scroll
a simple Bitmap anymore, so you'd have to keep a scroll offset based on a much
larger time
offset.

Mull it over for a day, if you are hopelessly stuck, then let me/us/the group
know and I'll
throw out some more code.
