Build a 27 3/4" x 23 3/8" exterior (22 1/2" x 18" illuminated area) wall mounted light box... I worked at a print shop a long time ago and pulled some negatives of a bat out of the garbage one day. That was about ten years ago. I finally got around to building light boxes to display the images. But you could use the same box to display any number of different things, including drawings on rice paper, negatives, inkjet prints on mylar... pretty much anything that light goes through, you know.
Step 1: get the materials
i made three of these, but you could make four with a little extra hardware.
4x8 sheet of 9/16" chipboard - $11
4x8 sheet of 1/8" clear plexiglass - $53
4x8 sheet of 1/8" masonite - $11
three 24" "preheat" fluorescent bulb holder thingies - $9.50 each
three 24" fluorescent tubes - $4 each
three power cords with no ends - $6 each
three switches - i used cool looking push button ones - $3.80 each
three packs of hook closer thingies(eye hooks with little arms) (3 per pack) - $1 each pack
four packs of 1" hinges (three per pack) - $1.75 per pack
three packs of 1/4" weather stipping (17') - $1.87 per pack
two foam brushes - $0.75 each
three 1x2x8' pine boards - $3.40 each
one tube of construction adhesive - $2.30
three sheets of rice paper (i didn't look at the size) - $2.50 each
two packs of 50' picture hanger gear (two sets of eye hooks and hangers plus wire in each pack) - $2.25 each
three bags of 1" corner braces (three per bag) - $1.75 per bag
adhesive felt pads - $3.28
total - $195.04
that's a lot of dough! but it really makes pretty much four lightboxes of this size. you'd just need a few more hinges and whatnot. there's enough of the big stuff (plex, masonite, chip board) for four.
