|1. Make a new image with a (for example) black background and put your type on it. I would recommend to use white type and colorize it later. Render your type layer and apply a bit Filters- blur- gaussian to get the type smoother.
|2. Reduce the file to the background, duplicate this layer and apply Filters- Pixelate- Mosaic with a 10 pixel setting. You’ll have to experiment with different settings, I found 10-12 pixel settings ideal for typesizes up to 100 pixel; above you’ll need higher settings.
|3. Set the opacity of your current layer to 50%.
|4.Apply Filters- Sharpen- sharpen 3 times.
Reduce to the background and you’re ready!
If you wish to have colour in it use Image- adjust- hue/satursation
> check the “colorize” box.
As I said, the effect only looks great on typesizes over 100 pix, you’ll get pretty transparent cubes and wonderful lightning.
