Need Ideas For Collapsible Lightbox For SECRET Engagement Idea :)
So, I've been dating a wonderful girl for a while now and in the relatively near future I would like to pop the question. I have a clear idea of how I'd like to do it but need some expert crafter advice to pull it off. My idea is a fairly innocuous guerrilla art installation which was inspired by the Banksy paintings he surreptitiously installed in museums. I want to surprise my lady by taking her to a museum and having an accomplice quickly deploy my idea in gallery for us to "stumble upon". My idea is for a lightbox, suspended from a tripod. The illuminated box will have pictures of us on all six sides and the top will open and the ring will be inside. I've made simple decoupaged cardboard lightboxes before, but this time it needs to be something collapsible which will fit in a messenger bag or something similar. My current thinking is to have the six sides of the box be plexiglass squares attached to one another with hinges. The sides would all be hinged to the bottom center piece. The front and two sides would then fold up to make the front and sides of the box. The rear piece would be two lengths of plexiglass attached to fold up and over making the back and the lid of the box (see very rough sketch below for my idea of how the pieces would be hinged). What I'm looking for is suggestions on:
What materials to use for the box itself and types of hinges (is plexiglass/lexan a good idea?) and how to attach the hinges to the box (glue?)
A way to make the sides all stay up once they are folded into place (I was thinking perhaps loops on each side piece you could slide a small dowel through or something)
And anything else you might want to suggest. Again the goal is to be able to bring this thing in without attracting attention, assemble it very rapidly, and be able to break it down quickly once everything is done. If I can pull all this off I'll document the process and post it here.
