I'm far too lazy to format out a Tip/Trick... Besides, I did it the lazy way, so it's not well-designed or anything... XAML:

<Window x:Class="BlahBlah.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
IsHitTestVisible="False" WindowStyle="None" AllowsTransparency="True" Background="Transparent"
Topmost="True" Width="50" Height="50" Left="{Binding X}" Top="{Binding Y}">
<Ellipse Stroke="Black" StrokeThickness="1" >
<Ellipse.Fill>
<RadialGradientBrush GradientOrigin="0.5,0.5">
<GradientStop Offset="0" Color="Red"/>
<GradientStop Offset="1" Color="DarkRed"/>
</RadialGradientBrush>
</Ellipse.Fill>
</Ellipse>
</Window>

Then just make a couple properties for X and Y, wire 'em up, set the DataContext, and make a 10ms DispatcherTimer:

private Vector Heading = new Vector(8, 0);
private Size ObjectSize;

void tmr_Tick(object sender, EventArgs e)
{
if (ObjectSize.Width == 0 && RenderSize.Width > 0)
ObjectSize = RenderSize;

double x = X += Heading.X;
double y = Y += Heading.Y;

Heading.Y += 1;
Heading.Y = Math.Max(-40, Math.Min(40, Heading.Y));

if (y + ObjectSize.Height > SystemParameters.VirtualScreenHeight)
    Heading.Y = -Math.Abs(Heading.Y);
else if (y < 0)
    Heading.Y = Math.Abs(Heading.Y);

if (x + ObjectSize.Width > SystemParameters.VirtualScreenWidth)
    Heading.X = -Math.Abs(Heading.X);
else if (x < 0)
    Heading.X = Math.Abs(Heading.X);

}

Kiddie stuff... Took five minutes, but then I spent another five tweaking it to make it look a bit better.

Well then how are we going to accidentally destroy the universe? Seriously, you need to think these things through :-D
