- A new “Necomimi” consumer EEG product—robotic cat ears that move in response to brainwaves—was highlighted as a potential driver for mass-market, low-cost EEG adoption.  
- DIY repository activity: kanzure posted updates to the lolcad project at http://diyhpl.us/cgit/lolcad and reminded users of the large physics-paper mirror at http://diyhpl.us/~bryan/papers2/.  
- Discussion of open-source design abstraction for nanotechnology: eudoxia proposed that, with proper tooling, nanotech could follow an open-source software model; kanzure pointed to the SKDB framework (http://gnusha.org/skdb/) as relevant reading.  
- Rocketry and space-systems links shared: NASA’s open-source GMAT mission-analysis tool (http://gmat.gsfc.nasa.gov/), Portland State Aerospace Society (http://psas.pdx.edu/), and curiosity about SpaceX pricing for Google Lunar X-Prize teams.  
- CAD workflow debate: RapCAD (http://www.rapcad.org/) was presented as an alternative to OpenSCAD; kanzure critiqued its author’s conflation of 3-D rendering with true CAD requirements.  
- Presentation-tech troubleshooting: kanzure experimented with HTML/CSS/JS slides for displaying code, sought cross-browser font-sizing fixes, and received screen-shot feedback across multiple resolutions and browsers.
