you may wish to take advantage of the few help files that are available 
under Gem/help...you could use any of the following:  [pix_add], 
[pix_composite], [pix_takealpha], [pix_mix]...or you could have two 
layers behind one another and send each a different [blend <, such that 
one is the inverse of the other...

...which brings me to a broader observation:  I think we need to be a 
little clearer about what an object does in the header & implementation 
files:  there are at least 3 headers that say "Add two images together" 
and at least 5 that say "Change the overall gain of a pix"!  Plus, it'd 
be good to require a /help patch for any new object:  I know I've been 
lax about that, but promise to do it from now on (really!)  ;-)

...yes, puzzle works with any input:  it just divides the incoming 
image into user defined sized squares, which can then be shuffled 
around via bang...as far as difference between video and tiff, tiff is 
a single image, video (as concerns gem) is a live camera input/stream 
of images...

...don't use multimage much myself, I like moving images alot right now!
