My question is not about photography. I hope that is OK. I bought a box of PinBlock building blocks for the grandkids. (www.pinblock.com) They are a little like Legos, but much simpler. One of the things they are good at is building pixelated versions of images. Here's an example from their website: The problem is that they do not provide any software for generating the templates or maps. So the kids are left to wing it freehand. That's OK, but tedious and error prone. I found some pixelation software, but there is another problem. In order for a flat project to stay together, each row of blocks must overlap the previous one by half a block so that they lock together. Otherwise, it is just a bunch of independent vertical columns that are loose. Here's an example of a Mickey image with "regular" pixelation: And here it is with offset pixelation: Can anyone recommend software that will pixelate an image at various resolutions and with the cells offset as in the second example above? It would be great if the software would also convert each cell to a single homogeneous color that best represents the colors in that cell. Thanks for any help.
