What It Is

Metal Heart is a personal generative art and interactive project website run by software engineer Marten Silbiger. Rather than a conventional commercial SaaS tool, it is a geek-oriented blog that combines physical LED art installations, virtual VJ visual creation, and in-depth technical tutorials. The author focuses on creating “video instruments” that evoke the feeling of musical performance, with projects spanning both software and hardware and showing a strong mix of hacker spirit and artistic expression.

Core Dimensions

• Tool/Service Type: A personal open-source project and resource blog. Its main outputs include physical interactive artworks, such as the BERMUDA ceiling installation with 25,000 LEDs, as well as virtual visual plugins.
• Core Features: The site mainly offers a series of FFGL effect plugins for the VJ software Resolume, such as Pixelsort XTC and Hexagon Mosaic, along with detailed tutorials on FFGL plugin development. It also includes VJ loops and 3D modeling showcases created with Blender and AE.
• Export & Compatibility: The plugins are primarily compatible with Resolume Arena 7. The creative workflow is closely tied to industry-standard tools such as Blender, After Effects, and TouchDesigner, while the technical stack includes C++, OpenGL, and Arduino, making it friendly to professional creators.
• Collaboration & Resource Library: The author has open-sourced code and documentation for some projects, and explicitly welcomes collaboration and co-development, such as recruiting helpers for the BERMUDA project. The resource library is medium-sized but focused and high-quality.

Pricing & Licensing

The website does not mention any commercial pricing. The author emphasizes that they “try to include documentation and source code,” reflecting a clear open-sharing ethos. No explicit license is stated, but the materials appear to be intended for free learning and use by default.

Pros & Cons

Pros: Strong hardware-software hacker spirit; Resolume plugins fill gaps in niche visual effects; open-source code and FFGL development tutorials are highly valuable for learning.
Cons: As a personal project, it lacks commercial-grade support and stability guarantees; the technical barrier is high, with C++ and OpenGL requirements excluding many purely artistic creators; the website uses a traditional blog format and lacks systematic search and organization.

Who It’s For

Best suited for VJs, digital artists, interactive installation developers with some programming background, and technically inclined creators who want to deeply customize Resolume effects at a low level.
