EvoLisa - My own version

It's an old idea by now, can we recreate the Mona Lisa with fifty polygons by using random changes? The idea and original implementation by Roger Johansson can be found here.

So, how does it work? You start with an source image. Then you create an empty image. We keep on doing small changes to this image. In my case this is one of these changes:
  • Recolor our polygon
  • Change the position of one of the polygon points
  • Add or remove a new point to our polygon
  • Add or remove a new polygon
  • Switch two polygons

After each action, we take a look and check if the newly changed image looks more like the original image by comparing each pixel. If it is, we continue using this one. If it's not, we discard the changes.

Looks like a fun project! So I built my own version from scratch eight years ago, reusing some of the same ideas. Here's my result using the Mona Lisa:

Mona Lisa with 50 polygons:

You can see that it's the Mona Lisa but the details around the eyes and mouth are really missing.

Mona Lisa with 200 polygons:

Ah, that looks a lot more like it!
And now I want to pick it up again and make some improvements! Let's see what we can do...

Welcome back

Seeing my World of Warcraft account getting hacked wasn't much fun but it does have one positive side. Since I had to pay €15 to get my deleted items back I decided to log in a few times this month and see what changed. I haven't played WoW since April this year so there's quite a bit of new content to go through. And of course I wanted to say hello again to all the friends I haven't spoken to in months. As I logged in I was quickly greeted by some of my guild members. Time is never standing still so I wasn't surprised to see that my guild looks nothing like it did half a year ago. Roughly half of the people I enjoyed chatting and playing with had all decided to join a guild that was more to their liking. Only the officer team seems to be relatively intact. The player gap has been filled in with lots of new players but it doesn't feel like the same guild. I had a chat with the old officers and my friends from ancient times. In this short time I even got a few

Circumventing the Steam Regional lockin for Europeans

Thiefsie at rps.com found a nice way to get the steam games in pounds. I tested it and it works! 1) Put ?cc=uk after a title. You'll now see the prices in pound. 2) Change your country to United Kingdom. That's it, you can now buy the game in pounds. Possible to save quite some money this way. Left 4 dead 2 costs €37.49 compared to the us £22.5(~€24.5). And the THQ complete pack costs €49.99 as compared to £26.49 (~€29.2). As always with these things: use at your own risk. It's probably not going to last very long.

Buy fast, regret even faster

When the iPhone was lowered from $599 to $399 a few months after its release it caused a small outrage amongst its early customers. The new price made sure that more people can afford one. But everyone who bought it at the $599 price point felt like he was getting screwed by Apple. And of course quite a few who did have the new technical marvel also had a blog about technology where they could vent their anger. Imagine walking past two stores. In our first scenario you see a car you've always wanted for $10.000. Then you walk past the next store and you see it priced at $12.000. You're happy, you did the smart thing! In the second scenario you see the car at $9.500. The next store has the car at $8.000. You're mad because you feel like you paid too much for the car. Even though you paid less in the second scenario you're not happy. So I find it weird to see thee huge discounts on games these days. Here's a few examples: Dragon Age . I've bought Dragon Age
