-This tutorial is a work in progress and will be updated as I get more screenshots and images.  I am by no means an expert and if you know of a better way, feel free to join us [[https://talk.hackspace.ca/t/laser-etching-a-full-color-image/3306|in the Talk thread]].
+This tutorial is a work in progress and will be updated as I get more screenshots and images.  I am by no means an expert and if you know of a better way, feel free to join us [[https://talk.vanhack.ca/t/laser-etching-a-full-color-image/3306|in the Talk thread]].
 The purpose of this tutorial is to walk you through the steps required to convert a full color image into something the laser cutter can work with to etch the image.  For the sake of this tutorial, I am using [[http://www.gimp.org/downloads/|Gimp]] which is a free alternative to Photoshop, an image I found on Google Images, and 6mm baltic birch from Windsor Plywood. The power settings I suggest are low enough that they should work just fine for 3mm if that is what you have on hand, but feel free to use up a piece of scrap from on top of the material storage to try this.  You will only need a piece that measures 3.5" x 7" so there will almost certainly be a piece big enough there to try this for free.

   * **Experiment**:  How will this look on leather?  It could make a REALLY fun project to etch art like this for a leather wallet
   * **Experiment**:  This is art of a larger project to incorporate all of the characters from Big Hero 7 into an image for a gift so my next step is going to be a much larger image which I suspect will require multiple sections at different index settings in order to get the most "resolution" out of each character in the final etch.  This may require the image itself be sliced into multiple files and reassembled on lasercad, experimentation to come.
+  * **Hyperdither**:  There's another dithering method that requires further experimentation: [[http://www.tinrocket.com/content/hyperdither/|Hyperdither]]! Source code [[https://github.com/tgray/hyperdither|here]].
