Comment(by walter):

 Good point. I'll look into adding the new block (probably not until
 after feature freeze, alas). In the meanwhile, you could try this code
 loaded into the programmable brick (the one that loads Python code
 from the journal):

    # clear canvas without reseting any turtle parameters
    rect = gtk.gdk.Rectangle(0,0,lc.tw.turtle.width,lc.tw.turtle.height)
    lc.tw.turtle.gc.set_foreground(lc.tw.bgcolor)
    lc.tw.turtle.canvas.image.draw_rectangle(lc.tw.turtle.gc, True, *rect)
    invalt(lc.tw.turtle,0,0,lc.tw.turtle.width,lc.tw.turtle.height)
    return

 One thought I had is to make the clean brick just clear the screen
 (and stop any media that is playing) and let the start brick do the
 reset. I wonder how many TA programs would break? (And I would have to
 make the start brick be able to be connected in line. Currently it
 only can be positioned at the top of a pile.)
