that's a fun project; i have shot through a small kaleidoscope (with my
old point and shoot) and simply cropped the photo, with enjoyable
results; can't easily lay my hands on an exmple; i'd think a Q would be
a good choice
The smaller lens would certainly make is less expensive.
of course the image a kaleidoscope produces is pretty deterministic, at
least if the lens is perfectly centered, so one could create even higher
resolution results with an appropriate digital image image
transformation; it seems to me it's just a step and rotate, with a
certain amount of light fall-off …
True, but I find I do a lot of composition by aiming the lens other than
axially. A friend of Zab's does digital kaleidoscope art. A bit of
google and I found her web page:

here's a technique which looks like it could be adapted to make a proper
three-mirror kaleidoscope:
