ASCII Shapes - Ben Mikek

Tutorial:

Draw a circle with r=5: drawWide (Circle 5)

Draw two right triangles beside each other: drawWide (Beside (RightTriangle 7 7) (RightTriangle 7 7) BMiddle)

A snowman (check out the examples section of shapes.hs to see how it is constructed): drawWide snowman

A shape vaguely resembling a dog: drawWide dog

A heart: drawWide heart

The text "GOOD LUCK!": draw goodLuck

A Sierpinski triangle: draw (sierpinski 7 5)

draw produces an IO in which each unit represents one character; so draw (Square 5) produces a 5 x 5 grid. This function is recommended for use with square-character fonts.

drawWide doubles the width of the output, so that draw (Square 5) produces a 10 x 5 grid which looks like more of a square on most terminal fonts.
