Lots of photographers are getting excited about the Light Blaster from the USA that enables you to project an image onto a subject or a background.
It is small, portable and it works with a hot shoe flash as a light source and a standard (D)SLR lens for focusing. The fact that it uses a standard lens means that you can control the size of the projection – 35mm to blast an entire wall; 200mm to paint a heart on a chest.
Its applications are only limited by the imagination. There are three packs of pre-made standard images you can buy from the manufacturer but the best part is that it can use regular 35mm slides. Your 35mm slides. Your 35mm slides created with your digital camera or artwork created on your computer.
