🕶️ A view of its UI while MIDI music is playing. Notes are represented by colored bars (depending on the type of instrument) descending from the top of the screen, corresponding to the notes played. A bar (retractable when the mouse is no longer hovering over it) at the top of the screen displays the song's progress. 📚️ Neothesia is a (fork of Synthesia, and a) libre, multi-platform, GPU-accelerated MIDI visualizer that can be used as an (elegant) MIDI player or to quickly learn to play the piano. It takes musical notes from a midi file as input and displays them as colored blocks falling onto a virtual piano.

🕶️ A view of its IU (on a dark theme) with a partial map of Normandy (France) on the main section, with a signposted itinerary and buttons on either side of the map to set the parameters for what the user wants to appear on it, and more general parameters on the right. 📚️ uMap is a libre, multi-platform tool to customize maps with OpenStreetMap layers in a minute and integrate them into a site. The user selects the type of map desired and enters points of interest (markers, lines, polygons, links, images, ...), chooses the license of his data, save his map online (prior registration required), then shares his dynamic online map on the site of his choice. The editor allows many customizations (colors, icons, minimap, ...). Excellent and libre!

🕶️ A view of its UI (v.1.6.0) during a game on my PC, showing on the main board the game with its suggestion system (in red, 2 white pawns threatened one by the black rook and the other the black knight, while it is strongly suggested to move my bishop to D6 - threatened by the black Queen in A5). On the left, the online help and below the control and analysis of the Stockfish engine, and on the right, the moves played and various display areas. At the top are the menus with various command shortcuts. 📚️ ChessX is a fork of Scid & a a libre and multi-platform database and an interface, allowing to study the game of chess. This very powerful tool allows to consult from its interface similar games played by grandmasters (it can use several databases simultaneously), but also to analyze the current game and perform many operations (training mode, support of Nalimov and Syzgy databases, ...). It is intended for learning chess via the analysis of chess databases or an AI, so the game is solo (IAs to be installed separately) or possibly two players in hotseat (but this is not its vocation). It supports the CECP & UCI protocols.
