pydance is a dancing game written in Python, formerly named pyDDR. The
idea is simple. There's a floor mat with arrows, and the game scrolls
arrows up the screen to the beat while playing a song. When the arrows
reach the top of the screen (not sooner and not later), the player
hits the corresponding arrow on the pad, and given that it's hit on
time with the beat, points are scored. Based on how well the dance is
put together, s/he is graded at the end of the song. Both keyboard and
mat play are supported.
