Nako is a version of the memory game Concentration that runs on the Nokia 770 which Jakub Pavelek coded. Jayne, our six-year-old daughter, loves playing Nako but some of the landscape photo pairs in the default tile set are too similar for her level of observation.

Jakub has worked up a version of Nako which permits you to supply your own images and to switch between different sets. The illustration here shows some of our five-year-old photos of Jayne as well as scenes from her native Cambodia (and the director of the AOA orphanage outside Phnom Penh).

Now the images mean something to her, and even similarly composed pictures of family and friends will be easier for her to distinguish (oh, I’ve got several more tile sets to create before her birthday on Sunday, at least one for each of the last five years — there’ll be lots of images of faces).

Construction of a tile set involves creating a single bitmap 2100 pixels wide by 70 pixels tall, picking and sizing 21 images each 100 pixels wide, and placing them side by side, as you can see below. The BMP image needs to be given a “.tileset” extension and placed in your Images folder for Nako to see it.

Clicking the arrows in Nako’s sidebar switches you between different tile sets. It’s hard to tell from this illustration, but the graphic shown there is the upper left quadrant of the dancer in yellow — the leftmost image in my .tileset file. I’ll probably change the photo in first position with one that has a clearly identiable feature in the upper left.

You can download the new 0.2.0 version of Nako 0.1.11 experimental version of Nako (this version closes if you try to switch to another application) from this page: koti.welho.com/jpavelek/tmp/770/

Thanks, Jakub!

Updated: 0.2.0 is now available.
