  Since their definition in 2010 by Zagier, quantum modular forms have been
connected to numerous different topics such as strongly unimodal sequences,
ranks, cranks, and asymptotics for mock theta functions near roots of unity.
These are functions that are not necessarily defined on the upper half plane
but a priori are defined only on a subset of $\Q$, and whose obstruction to
modularity is some analytically "nice" function. Motivated by Zagier's example
of the quantum modularity of Kontsevich's "strange" function $F(q)$, we revisit
work of Andrews, Jimenez-Urroz, and Ono to construct a natural vector-valued
quantum modular form whose components are similarly "strange".
