Explore Ryven: Visual Python Scripting Made Interactive

Tired of plain black‑on‑white code? Visualize your Python scripts with Ryven, a tool that lets you see each step—from loading an image and resizing to applying bilateral filters.

Ryven, created by first‑year ETH Zurich student Leon Thomm, provides a visual editor where scripts consist of variables, flows (or graphs), and logs. Run Ryven.py to launch the editor, then import node packages via File → Import Nodes and load *.rpc files.

Prerequisites

Python 3 (recommended 3.8+)

PySide2 (recommended 2.14+)

The tool supports two algorithm modes:

Data Flow: Every data change propagates forward instantly, updating all connected nodes. Adjusting a slider immediately refreshes results in downstream nodes.

Execution Flow: Data updates only when a node explicitly requests output, triggering updates in affected nodes on demand.

Leon Thomm, an ETH Zurich first‑year student, describes himself as an “amateur programmer” focused on human‑computer interaction and visual programming. The project’s source code is available at https://github.com/leon-thomm/Ryven .
