On a distant trip to Glastonbury, I saw my first infinity candle and it is a perfect meditation tool. You can buy these quite cheaply, but if you fancy making your own you'll need an ordinary (reflective) mirror and a one-way mirror which are held parallel to each other in some kind of stand. There are a number of tutorials on the net - I like this one 'cos it came with pictures.
I used gaffer tape (aka duct tape, or, for the musos among us, roadie tape).Open the hinge so the mirrors are approximately at right angles (90degrees). Place a candle in the centre (fairly close to the hinged edge) and have fun adjusting the angle to get a different number of reflections.
