I have an embarrassing number of dvd's and cd's; I think it's up to about 600 - 800 now... I have long ago started putting the majority in cd binders, but I have a really nice room dedicated as a library and I'd like to make the dvd's more accessable.
What I was thinking of was a podium that has a motorized spinner that could store all of the dvds in the body. You could then scroll the entire catalog forward and backward to find what you want.
My carpentry is good enough that I could build the podium no problem, but I needed help on the guts... If there is a kit that someone knows of or has any ideas it would really help. I have included a (pretty terrible) sketch of what I had envisioned...
[EDIT] I'm adding links to this picture and this Youtube demonstration of what I believe this user to be referring to.
