I was interested in building this:

I've read up on miter joints but was wondering if anyone had
suggestions on how to create a miter joint that is easy to assemble and
disassemble. Everything I've read on strengthening miter joints (and
miter joints in general) involves glue.

If a miter joint isn't the way to go can someone suggest and easy to
assemble and disassemble joing for a project like this?

Is there a system like the methods IKEA uses available in hardware
stores? I'm looking for something like IKEA joints for miter joints.
I tried to find a link to IKEA joints with no luck. The joints I'm
talking about have metal piece you screw into one side and a rotating
latching mechanism that captures the metal piece on the other side.

Suggestions?
