You Decide What We Build Next
Simulations4All isn't just a library of tools - it's a community. Every week, you vote on which simulation gets built next. Have an idea? Propose it. Love someone else's idea? Vote for it. The winning proposal each Friday becomes our next project, and the proposer gets credited on the finished simulation.
1. Propose Ideas
Submit one simulation idea per day. Describe what you want to learn or teach.
2. Vote Daily
Cast one vote per day for your favorite proposal. Change your vote anytime.
3. We Build It
Every Friday, the top-voted simulation wins. We build it and credit the proposer.
