# Summary of IRC Log from #hplusroadmap (June 7, 2011)

• Discussion about ultrasonic brain stimulation technology, including references to William Tyler's research on transcranial pulsed ultrasound that can stimulate brain circuits with approximately 2mm lateral functional resolution.

• Several scientific papers were mentioned regarding sonoporation (ultrasound-induced cell membrane porosity), with links to research on how ultrasound affects neural tissue.

• A Kickstarter project for building an open-source Bussard fusion reactor (polywell) was shared, representing early crowdfunding efforts for fusion technology development.

• The Seesaw Compiler from Caltech's DNA lab was linked (dna.caltech.edu/SeesawCompiler/), likely related to DNA computing or molecular programming.

• A controversial event called "ModCon V" was discussed, which claimed to offer extreme body modification procedures at a "secure facility in Latin America," raising ethical and safety concerns.

• Augmented reality technology was discussed, specifically the Vuzix Star 1200 AR glasses, with commentary on their limitations and questions about why virtual retinal display technology (first invented in 1986) hasn't become more widespread.

• A project involving mapping Austin's caves using Kinect technology was mentioned as part of Matt Goodman's work at Craneium.net.
