You can search YouTube for examples, but here are a few great clips, some of them still pop in to my memory even today:
- Angle dance (... have some geometric fun)
- Tesslations (ריצופים)
- Apple rap "I think I see the problem/ I know what you mean...)
- Graph of Love "Just glance at this graph my friend/ Romance shows an upward trend/ I'm singing the praises of/ a thing called the graph of love."
- Ghost of a Chance
