On November 9th, 1969, the San Francisco Chronicle received a letter from the supposed Zodiac Killer providing details of his crime not yet known to the public. Between taunts, delusional statements of purpose and laborious descriptions of crimes, he noted his use of fingertip guards:

"2 As of yet I have left no fingerprints behind me contrary to what the police say in my killings I wear transparent fingertip guards. All it is is 2 coats of airplane cement coated on my fingertips -- quite unnoticible + very efective"

Pokémon was many things for me in 1997. As of the past week, it's some new things to the whole world.

When earlier this year, Mike Hearns; a prominent former developer and voice for bitcoin stated that Bitcoin had failed, and that its price would drop in the near future, many people listened, and sold their cryptos, in a panic sell, fearing the worst. But not everyone - certainly another prominent voice and developer Gavin Andresen, offered his confidence, and I myself, was quick to offer a rebuttal in this article: Bitcoin will be here to stay, longterm..

Fast forward to the middle of the year, and we are beginning to see an emerging pattern with increasing clarity. Just 2 days ago, the price of bitcoin hit 570 USD, on one of the leading bitcoin exchanges - Bitfinex. This figure, is the equivalent of just under $800 AUD. Such heights on the bitcoin price have not been seen since times of the bubble.

When Neil deGrasse Tyson first started tweeting about the portrayal of science in pop culture, it was a hit. He filled his Twitter feed with live commentary on various movies, the first being Alfonso Cuarón's 2013 film Gravity, with the following statement:

"My Tweets hardly ever convey opinion. Mostly perspectives on the world. But if you must know, I enjoyed #Gravity very much."

Last time on the blog, we poked around indoor navigating -- a subject near and dear to my expertise, given I once spent eight months straight poring over all the ways one could navigate various luxury malls in Australia, the United States and the U.K. (Next time you're in a major mall and encounter a touch kiosk that will create paths for you, you may think of this blog.)

Last week I introduced the topic of artificial intelligence and technological singularities, and why they remain grounded more in fantasy than reality. We continue on that discussion today.

You've probably heard of Google's recent push for their indoor mapping product Project Tango -- they are probably the most notable company making forays into this technology, though they are hardly the first. Digital wayfinding is a new and booming industry, and it is prepared to push the boundaries on how people interact with and navigate spaces.
