Spirographs and Light Tunnels
This can be done using your dome tool or a hoolahoop with leds taped to the edge or even a square or triangle with leds on. hold the wheel/hoop almost point blank to the camera, then when you set off your exposure pull the wheel/hoop away from the camera for as little or as long as you like, this will create a light tunnel. An other way of doing this is to do the exact same thing but spin the wheel as you're doing so, fast or slow the results are different each times and produce interesting pictures.
Spirographs (IMAGE COMING SOON)
Remember spirographs? Yes it's literally that, but not on paper, this can most simply be done with your dome tool in almost the same way you used to do spirographs as a kid.
Get your wheel and just do something as simple as roll it in a straight line on the floor, you will notice it makes a nice pattern. You can add more lights, put them in different positions on the wheel, If you fancy taking if turther you can use different sized wheels, different lights and using different locations such as tunnels to make them more indertesing, you may have to modify you wheel on to a pole to get some harder to reach locations and using walls and ceilings.
