The initial version of this tiling app covers the 15 cases of pentagons that tile the plane monohedrally (i.e. with one type of tile). This Wikipedia article describes the tilings. Where the shapes have degrees of freedom these are parameterized (and parameters can be adjusted with sliders in left side panel).
The app is intended to support exploration of different coloring of the tilings and the use of different wood veneers for the tiles. The default color palette matches the illustrations used in the Wikipedia article. These colors can be changed as desired. They can also be defined based on a number of standard color schemes using a seed color. Images for tiles can be loaded in any standard graphics format and are stored using local browser storage.
Colors (or images) can be applied based in the isometry class of the tiles with an option to distinguish chiral pairs. This gives the coloring schemes demonstrated in Wikipedia. Alternatively the coloring can be based on the orientation of the tile, or simply with each tile colored independently.
The development was inspired by the Tiling Viewer Applet built in Java by Jaap Scherphuis. Currently nearly all the patterns demonstrated in Wikipedia are included.
