A little demo with a rogue-like optic using termbox-go
to simulate light spreading in an ASCII dungeon. 

Build:

    $ go get -u github.com/nsf/termbox-go
    $ hg clone https://s_l_teichmann@bitbucket.org/s_l_teichmann/termtorch
    $ cd termtorch
    $ go build termtorch.go

Run:

    $ ./termtorch

Usage:

    Use arrow keys or hjkl to move '@' around the screen.
    Press 't' to turn the torch on and off.
    Use '+' to increase the radius of the torch light
    and '-' to decrease it.
    To draw walls press ' ' (Space) to toggle the cell
    below the '@' between '#' and ' '.
    Pressing Escape or 'q' will end the demo.
