The clear method wipes the slot. It also takes an optional block that will be used to replace the contents of the slot.
# sample12.rb
Shoes.app :title => 'RC', :width => 100, :height => 80 do
def random_creatures
background rgb rand(256), rand(256), rand(256)
name = %w[loogink cy yar kamome shaha][rand 5]
image '../images/' + name + '.png', :left => 30, :top => 10
end
random_creatures
every(5){clear{random_creatures}}
end

The append and remove methods are also useful.
# sample13.rb
Shoes.app :width => 450, :height => 250 do
stack :margin => 10, :width => 200 do
subtitle 'Shoes ToDoList'
para 'Add a list.'
@add = edit_line
button 'Save' do
@notes.append do
para @add.text, ' ', link('delete'){|e| e.parent.remove}
end
@add.text = ''
end
end
@notes = stack :margin => 10, :width => -200
end
