Thanks to Jim Getz for drawing to my attention something that I must have missed when it appeared on AWOL: The Virtual Magic Bowl Archive.
It is a site for a project aimed at bringing not only digital images of the bowls (hopefully including Mandaic ones!), but also scholars working on these bowls, together into a virtual collaborative space.
They also have the coolest logo ever, mimicking the spiral writing characteristic of the magic bowls.
One publicly-accessible result already connected with this project is a prosopographic database of the Babylonian magical bowls.
