The "Sandbox" twist encourages a deep dive into fundamental musical concepts, potentially uncovering innovative sonic textures and structures that could define the next generation of indie game scores.
PROCJAM 2024: The Art of Generative Systems
PROCJAM, the Procedural Generation Jam, is a celebration of algorithms and automation in creativity. Scheduled from October 25 to November 4, this jam focuses on "making things that make things," whether it’s a game featuring procedurally generated levels, characters, or narratives, or an interactive art tool that creates dynamic visuals. Procedural generation (PCG) is a powerful technique that allows for the algorithmic creation of content, offering immense replayability, reducing manual asset creation, and fostering emergent gameplay experiences. From the sprawling, unique universes of No Man’s Sky to the endlessly varied dungeons of Spelunky, PCG has reshaped how games are designed and played.

The jam’s laid-back and welcoming ethos is crucial for a topic that can often appear daunting. It explicitly encourages the use of existing code and art assets, teamwork, and a relaxed pace, making it accessible to newcomers who might be intimidated by the technical complexities of PCG. This approach demystifies procedural generation, inviting participants to experiment with concepts like cellular automata, L-systems, Perlin noise, and Markov chains without the pressure of a hyper-competitive environment. For experienced developers, PROCJAM offers a chance to push the boundaries of PCG, exploring novel applications or refining existing algorithms. The extended timeframe allows for more ambitious projects and deeper learning, solidifying PROCJAM’s role as a cornerstone event for fostering innovation in generative design.
LSDJAM 2024: Navigating the Surreal Dreamscape
LSDJAM 2024 invites participants to explore the nebulous and often bizarre realm of dreams, inspired by the cult classic PlayStation game LSD: Dream Emulator. Running from October 21 all the way to March 1, this extended jam provides an expansive window for creators to craft interactive experiences based on dreams. The original LSD: Dream Emulator is renowned for its surreal, non-linear exploration of dreamscapes, devoid of conventional objectives or narratives, instead relying on emergent experiences and psychological resonance.
This jam encourages participants to delve into the artistic and psychological dimensions of dreams, translating their inherent unpredictability, symbolic language, and often fragmented nature into interactive media. Developers can experiment with abstract visuals, disorienting soundscapes, and non-Euclidean geometry to evoke the sensation of dreaming. The exceptionally long timeline of over four months is a significant feature, allowing for more ambitious projects than typical week-long jams. This duration enables deeper exploration of complex themes, more polished artistic execution, and potentially more intricate systems for generating dream-like states. It provides an ideal environment for creators to craft truly unique, deeply personal, or universally evocative surreal experiences that challenge conventional game design paradigms and push the boundaries of interactive art.
