A different way to browse the Biodiversity website (a website full of scanned books about biology subjects).
Instead of searching by topic or title, you use wooden shapes to build a plant. This will be used as a filter for the database. For example; putting up a round flower will make the application show only images with that kind of flower. The display time of each image depends on the amount of search results; the lesser search results, the slower the images move by.

You can set the main shape (branch, bush etc.) the shape of the leafs (long, irregular shaped etc.) and the shape of the flowers (pointy, round etc.).

Made using Processing and Arduino .
