Draw a glider and a block shaped like a cross.

Select the glider.

You can move this glider up and down and try different positions.
Press the X key to save this generation to the stack.

Use the space bar to watch.
Press the Z key to go back to the last generation saved.

For example

Then we get a yellow cell orbiting the block

If the glider is place above the block as showed below
