Kvass is fermented from old bread, and tradition reads it as thrift, turning what is left into something refreshing, and the flavour of village summers.

My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
