suddenly two handsigned XKCD comic strips spawned on our whiteboard at the metalab hackerspace (http://metalab.at).
nobody knows for sure where they came from but they are far too cool for normal frames so i made those boxes using our lasercutter, 4mm plywood, 3mm acryl, M4 screws and red paint.
i used the stencil std font to burn a "break glass in case of packetloss" notice on top and "XKCD.org" on the bottom.
you need a lasercutter..
the part on the right is the "glass" and needs to be cut from acryl.
the boxes should be cut from 4mm plywood
