I heart maps

I made a neat connection in the library map room the other day, and ended up rescuing a bunch of old geology maps that were destined for the recycle bin to use in art projects. With tools like Google maps available on everyone’s cell phones, the old printed-on-paper maps are gathering dust, I imagine soon only very few with historical significance will be spared from an end in the dumpster.

I have a history of rescuing geology maps – my aunt used to liberate cool maps for me from the throwaway bins at the Ministry of Natural Resources, where the big spool printers were constantly rolling off updated diagrams of extremely remote and exotic places.

I loved the swirls of landforms and mysterious markings – better than a lava lamp! Check out swirly lake Cawatose in La Verendrye in Québec – subject to tremendous shearing in Canada’s most ancient geological history, it looks like a giant’s thumbprint.


Follow the Red Dot

So that software that I wrote to track red things… now it tracks red laser pointer dots! I have a bit of finessing to do on the look of the lines, but the “system” more or less works. Below is a shot of some laser graffiti I captured by doodling 20 ft away on my back wall.

As an unintended neat side effect, I discovered I can track the blinking red lights of airplanes flying over. :) With a fisheye lens and a higher resolution camera, it might be really neat to show the air traffic corridors as a series of graffiti lines across the sky. More (cooler looking) stuff coming shortly!


Flagrant Product Placement

More playing with cameras – this is me testing a tool I wrote to find and track red objects moving through the field of view in realtime. It’s working great, but there’s some threshold values left to fiddle with – my ear is apparently red enough to trigger an object detection. (What’s black and white and red all over? Jason’s ear in this picture!)

This is going to be paired up with a red laser pointer and a projector for a drawing project – hopefully more on that shortly. ;)
