Hi Eric,

this looks very nice!  I just tried beamer for the first time,
this is very simple now.  Maybe I can drop powerpoint, at least
for some stuff.

I think we need a good beamer tutorial on Worg, including this
column stuff, and some text about image treatment.

Any volunteers?  Anything missing in Org that we should implement to
support this better?
