There are two areas of work to date for OBIBDs, to which introductions are given below.
The current search results are for 1-rotational designs here.
I have not given all the constructions here, just those which, so far as I can tell, are new, or are of particular interest to me.
OBIBDs considered from various viewpoints here.
This will initially be just applets indicating the constructions; the actual constructions are detailed in the original papers. Starthere.
