# Key Points from #hplusroadmap IRC Discussion

• Participants explored procedural generation for virtual worlds, discussing how deterministic mathematical equations could create vast explorable environments with minimal storage requirements, potentially evolving into tools for designing real-world objects.

• The group examined L-systems (Lindenmayer systems) in computational geometry, particularly how plant genomes can be mapped to L-system parameters to predict phenotypes and generate realistic models, with resources shared from algorithmic botany (http://algorithmicbotany.org/papers/).

• A technical discussion of brain-computer interfaces compared true BCIs (using EEG, fMRI, and microelectrode arrays) with devices that primarily use gyroscope and myoelectric data, noting current BCI technology's severe bandwidth limitations ("6 bits/min").

• The conversation covered Daeken's hack of the Emotiv EPOC EEG headset, with links shared to Emotiv's responses (http://emotiv.com/forum/forum15/topic879/), highlighting ongoing community efforts to extend commercial neurotechnology.

• Intellectual property concerns in consulting contracts were discussed, specifically regarding clauses that assign all copyrightable material to companies and how this conflicts with prior GPL2+ and Creative Commons licensing commitments.

• The group debated space exploration topics, including criticism of retired Apollo astronauts' perspectives on modern private space companies like SpaceX, and the historical value and legacy of the Apollo program.
