# Key Points from IRC Log

• A discussion about VR haptic technology occurred, with detailed exploration of a flexible suit made of hexagonal bubbles that could be inflated with fluid to create force feedback, likely using hydraulics rather than pneumatics to reduce springiness.

• Fenn shared a diagram (http://fennetic.net/irc/hex_bubble.svg) illustrating the bubble contraction mechanism and discussed using light-gated microfluidics for control, noting that force control might be more practical than position control for many robotics applications.

• There was mention of "writozymes" and light-responsive elements for transcriptional regulation in a biology context, referencing a thread on the DIYbio mailing list.

• A user mentioned being venture funded for an iPhone app, with concerns about excessive meeting requirements (minimum 2 hours daily) and plans for server stress testing to support up to 10,000 users.

• Discussion of MIT OpenCourseWare occurred, with a note that it lacks relevant neuroscience classes in audio format except for a "neuroscience of behavior" class.

• There was a brief mention that SKDB (likely a software knowledge database project) had been inactive for months, with no recent development.
