Taking Sudoku to the next level
Basic Sudoku is played with 9 symbols, which are generally the numbers 1 till 9. Other than numbers, these can be anything from 9 letters to 9 colours (for the rules, check out Wikipedia). I combined a "number Sudoku" with a "colour Sudoku" to obtain the Squobble Puzzle. This has some interesting consequences. For instance, only certain combinations of numbers and colours are possible. Also, the classic Sudoku tricks can be applied on numbers, colours or both, and even new solution methods can be found.
I included a beginner and expert level (if you're good they should take you about 5 and 15 minutes respectively), and the standard options: reset, choosing a puzzle by number or randomly. Moreover, every puzzle has a unique solution. Finally, to guarantee your satisfaction, dear reader, all of this was molded neatly into a Flash puzzle with drag-and-drop support.
Anyway, the list of features-to-add includes a charts system for best times and other records, a classic Sudoku page, etc. Whether I implement these will depend mostly on visitor feedback and the local weather forecast (a lot of rain means more features).

I made this ad for the Spanish deepline.net.

Movistar Art #1
Movistar España, the leading mobile phone operator in Spain, has launched a 75 million euro campaign to promote its new logo, a stylized letter "m". Since its start one month ago, the initiative has drawn huge attention from the public, mainly because of the air of mystery it was initially surrounded by.
Nevertheless, what was once new quickly got boring, and since the new image didn't really seem to boost sales, a new approach was taken this week in an attempt to make a lasting impression on the potential customer.
As reported by the Spanish national police, street violence has dramatically risen since the new posters started appearing everywhere. Soon more on this subject.
 Apparently some well known Spanish actress also participated in the campaign.

Matlab Art #2
Origin of the image: 1 frame of the evolution the output of a multi layer perceptron is going through while it tries to adjust the different curves to straight lines. In this case the adjustment was obviously heading towards an explosion so I stopped it at the time of the image.
First I did a test with a few songs on my pc. After the program trains itself with the songs, it takes a 5-second fragment of one of the songs, highly degrades it with noise and then tries to recognize it. It turned out to work just fine, and above all, very fast. Then I went for the heavier version, and fed 1000 different audio tracks into the training part of the program. To my surprise, it continued to recognize the music perfectly, in much cases up to noise degradation levels at which the human ear isn't capable anymore of recognizing it, which was nice.
That being written, if you want to get the Matlab code to play around a bit at home with,

Matlab Art #1
Origin of the image: real parts of the poles of the filters representing two fragments of mixed voices.

Let's eat some squobbles!
Previously, there were always 150 links available on the board, and the least popular ones were replaced with new suggestions. Since I want them all out of the board before switching to the new version, I changed a parameter so that from today on it will "degenerate" automatically. Every day a few of these 150 will be eaten by the archive, until there are none left. Let's hope v2.0 will be ready at that moment.

Here we we go then!
First of all there's my wicked internet experiment, Squobble. I won't explain on it too much now, since it's a pretty simple thing to understand. Moreover, its behaviour is still changing, so I will just comment the parts as they stabilize. In short, it's pure fun, leaning over to the crazy side. Then, there's the audio related investigation stuff I do, ranging from voice recognition to music processing algorithms. Pure fun too, but at least this matter is scientifically justified. And last and least there's a tiny bit on graphic design (mostly web design) just for the love of it. Anyway, a nice "Welcome to you, dear reader!" seems to be appropriate to finish this first post.
PS1: On the to do list: change the crappy template design of this page in something a little more neat.
PS2: Welcome to you, dear reader!
