- A web-accessible nanotube structure generator (tubegenonline.html) and a Java-based nanotube visualizer (jnano.html) were shared as open tools for atomic-scale design.  
- The “Human digestion machine” from cloaca.be was highlighted: it inputs foods, stomach acids, and enzymes and outputs feces, serving as a literal model of the human GI tract.  
- A Cornell “grasshopper-ball” jumping robot for space exploration was noted, with speculation that Hod Lipson’s lab could adapt Fab@Home tech for Mars fabrication.  
- A paper on “graph pegging” (arXiv:0804.1095) by kanzure’s math teacher was introduced, exploring checker-like moves on graphs to reach any vertex and relating the concept to graph pebbling theory.  
- A debate unfolded on whether open-money systems are a useful bridge from today’s scarcity-based economy to a post-scarcity gift economy, with kanzure arguing money itself is unnecessary.  
- Provigil (modafinil) was discussed as a cognitive enhancer; ybit cited a Rhodium archive synthesis guide and lamented the $300/month cost, prompting kanzure to suggest bootstrapping a DIY synthesis lab.  
- RepRap’s hyperbolic growth was claimed; genehacker was encouraged to write a short paper and post it to arXiv for “the lulz.”  
- Links to PCB fabrication resources (hdihandbook.com) and miscellaneous atomic-coordinate libraries (projectaten.net) were dropped for hardware prototyping reference.
