Shoes 4 Ski Jumping Game. Inspired by [Sebastjan's post](http://librelist.com/browser//shoes/2013/1/13/thank-you/) in Shoes ML. But, this is not a game, just a tiny example to learn Shoes 4. ;-)
class Skier
def initialize app
app.strokewidth 2
@x0, @y0 = 0, 20
@img1 = app.oval @x0 + 25, @y0 - 20, 5, 5
@img2 = app.line @x0 + 5, @y0, @x0 + 25, @y0 - 15
@img3 = app.line @x0 + 5, @y0 - 13, @x0 + 20, @y0 - 15
@img4 = app.line @x0, @y0, @x0 + 30, @y0
@img5 = app.line @x0, @y0, @x0 + 30, @y0 - 10
@img5.hide
