I feel like this thread, along with other GDI threads, isn't getting the attention it deserves.
Maybe it's just me, but I think things like this are really cool.

Odus, trvp did this with numbers as well. Maybe add that?

Odus is my son, I think I deserve a shoutout too!

There was a time a while ago where I made a thread to take requests for GDI controls.

Stupid question but with your example. How would we go about using a combobox to change the color and also change the size of the objects?

I was actually going to 1up him and allow a custom array of characters, will update OP shortly.

Not at all. The Colors property is of type color array, so you can change the colors using that.

In the demonstration, I used a Dictionary of String & Color() to hold my colors and set the ComboBox's data source to the dictionary. So the keys (string) front the ComboBox items but the value is really your colors (color()). Like so:

Code 
Dim cd As New Dictionary(Of String, Color()) From {

    {Color.Red, Color.IndianRed, Color.DarkRed},

    {Color.Green, Color.GreenYellow, Color.LawnGreen}

}

ComboBox1.DataSource = New BindingSource(cd, Nothing)

ComboBox1.DisplayMember = "Key"

ComboBox1.ValueMember = "Value"

When using, I just cast the selected item to a KeyValuePair and set the Colors property to its value:

Code 
MatrixFall1.Colors = DirectCast(ComboBox1.SelectedItem, KeyValuePair(Of String, Color())).Value

For the objects' size, use the BlockSize property which is of type Size. So in your NumericUpDown ValueChanged event, set the BlockSize to their values:

Code 
MatrixFall1.BlockSize = New Size(Convert.ToInt32(NumericUpDown1.Value), Convert.ToInt32(NumericUpDown2.Value))

This was for a demo so I didn't bother changing the control names. I'm glad so many people like it though!
