Hrivna is a local ukrainian currency. As you can know, it isn't stable and people preffer to save money in US Dollars or Euro. 7 times per day my resource parse currency rates for each ukrainian bank. As a result I provide an information service for wide currency operations like selling and purchasing, statistics, and bank dinamics visualizations. Also I handle black market as well as real banks rates.

The service is a simple tool and visualization for musicians. It allows you to choose a harmony, leading note, pentatonic, speed and note's length. Aftewards service will draw a keyboard with highlighted keys which you can use in your composition and will play a simple generated melody in this harmony. Under the hood it was an experiment with Web Audio API and MIDI.js. For a moment it doesn't play well with mobile devices.
