I used to find no-caps typing frothingly annoying, but I think the internet has ruined me. The lost & found books were both fascinating to make–on the face of them they have very little in common (save the rock crystal knobs) but both of them play with negative space in a way I found entertaining. The found book, a tunnel-bound book depicting a cartographical representation of an excavation, is only effective to the viewer because the layers are separated from each other by a specific amount of space; the focal point of the whole thing is in fact what is not there, or lost, the physical absence of paper within the hole. The lost book, stab-bound, is in itself not particularly interesting; it’s the cutout voids in the pages (what was once there is now lost) through which are strung chips of stone (things that are found) which make it both pretty heavy and also spatially interesting.
Neither of them are entirely discretely focused on lost or found but, as I think Spenser was pointing out, the definitions of both words are somewhat relative.
