Hey Adam -
Wondering if Clan's box might of been one of these-style
(First pic: System was designed by Terry Michaels of Laser Artistry, (now, 'OOB' ) and is his pic as well - a very fine example of 'old-skool' (just teasin, Pat!) craftsmanship!
...And as to the 'rationale' for these types of systems, the rest of the pix are for all of the dpss-shoebox 'nu-skoolers' here
**NOTICE: NOT AN INSULT!!** I've made my share of 'shoeboxes' too, and they're fun!) as a wise-old 'old-skooler' once said to me:
..."this is how it's done, son!"
The advantage multiple-position-projectors give you is the flexibility
(with 50/50 splitters) to 'share' and do both beams
(which are HIGHLY underappreciated in the PL-arena, in my opinion! ) fx
(like machita) and graphics/aerials/atmospherics- at the
SAME TIME..
keewwl, eh?
- and as the next batch o' pix will show,
(along with 'proof' of some of my 'shoebox' werk ) these beam-position systems
need-not be GIANT - all depends on the 'size of the wand' you're using to make the magic with...
njoy...

(but sorry, Pats' still wins...)
