SAN FRANCISCO (CBS SF) — A San Francisco artist is looking to spice up your daily commute. Forget sitting; you can now swing on some BART trains.

Hunter Franks started installing these unofficial attractions in BART cars. As some videos posted on social media show, passengers are taking full advantage.

In addition to the swing, Franks also created a few other installations including a hopscotch board near a ticket machine.

There has been no word yet on if BART will remove any of his work.
