Yes, it is most certainly diminished 7th. Bunch of minor 3rds stacked on top of each other. Basically play around with something like that. Although Rusty here and most guitarist opt to only stick with the shape on only 3 strings down from the high E.

[EDIT]

The point though is that you can take that exact shape and use it every 3 frets high or lower all over the guitar. A diminished 7th chord is symmetrical which is why it's so cool and easy to visualize on the fretboard. =P
