Update November 2020
I have just been awarded the 5000 Euro ET outreach award of the Royal Holland Society of Sciences and Humanities through the de Zeeuw-van Disshoeck fund for developing the TULIPS project further. For more information, see the press release: original in Dutch or English translation
TULIPS, the Tool for Understanding the Lives, Interiors, and Physics of Stars, helps visualize the physics of how stars evolve over time in an intuitive manner. Instead of complex diagrams, stars are represented as circles that change in size and color over time.
