v0.1.0

• A game of Tetris for each trunked system, played by the computer, its pieces made by the
  messages on the system's control channel: a channel grant makes a T, O or I, an affiliation a
  J or L, a registration or deregistration an S or Z. Pieces come out of a bag of seven, so each
  comes as often as any other however lopsided the messages are, and only the first fitting
  message after a piece appears makes the next one, so the game goes at its own pace.
• NES Tetris's screen, with its colors changing with the level, and its scoring.
• A computer player that slips now and then, so games end (about half an hour each at the
  relaxed pace) and start again by themselves.
• As many games on the screen as fit; with more systems than that, they take turns.
• Message boxes: TETRIS!, the level, a new record, game over, a new high score.
• One high score table for every system, with the date, between games and under 🏆.
• Korobeiniki as chiptune music, sound effects, and live audio, each on or off. The music goes
  quiet while the radio talks.
• Full screen, for a wall or a spare monitor.
