A mounting includes a connector connecting a first base to a second base so the first base can rotate about a first axis and the second base can rotate about a second axis. The connector includes aligned first links extending in parallel planes at right angles to the first axis and plural aligned second links extending in parallel planes at right angles to the second axis. Slots between the first and second links respectively receive, in an interleaved manner, (1) aligned third links of the first base, and (2) aligned fourth links of the second base. The first and second links extend in opposite directions from a central plate of the connector.
