My first original desktop application, PixelTiles was created for a use case scenario where you want to create your own minecraft textures of 16x16 pixels, with options of many various size groups for other uses. Included is a color selection and saving tool that can be used to copy and paste RGBA and HEX color codes for outside use. My kids love using this program as a general painting program. The biggest challenge I have with PixelTiles is including transparent empty space. To incorporate this, I will need to redesign the core of the program at a later time. For now, transparency works well with overalying colors on top of eachother.
