Tcalculus(mostly obsolete, to be moved towards the Timed Monad Stream library)The Tcalculus is a domainspecific language prototype, presently embedded in Haskell. It aims at experimenting tiled programming for the design and implementation of reactive temporal media systems. It is based the fairly rich algebraic model of overlaping tiles.The current implementation can roughly be described as:

Currently the Tcalculus V1.0 is in alpha version. Its complete
code is available here and realtime experimentations in the field of live music can be
found there.
