Today, the most common tool for complex maths visualization in the classroom is the TI-84+. Scientists, researchers, and other professionals who implement calculus in their work may rely on more complex toolkits like MATLAB. Though these tools offer broader functionality, they are similarly if not more unintuitive than their handheld counterparts. Visualization plays a crucial role in understanding, mastering, and improving upon mathematical concepts, but today's standard interfaces frustrate and alienate many individuals, creating an excessively high barrier of entry to higher level math studies. Calcflow shatters this interfacial bottleneck by enabling users to interact directly with complex equations in physical space. Users can manipulate inputs and parameters and observe changes to 3D visualizations in realtime.
