Ice text is an unusual way to present common fonts, and can be used in different colours for slime or alien effects.
Go to File > New and create a new image, then go to Image > Mode > Greyscale.
Click the text tool (looks like a T), then type the text you want onto your image.
Next, go to Filter > Noise > Add Noise; make sure the Amount is set at 145 and Distribution is Gaussian then press Ok.
Go to Layer > Flatten Image, then Filter > Pixelate > Crystallise and set the Cell Size to ‘3’.
Now go to Filter > Stylise > Find Edges and then Filter > Blur > Gaussian Blur, and set the radius to 0.7. By now you should have something which looks like this:
Go to Image > Rotate Canvas > 90 CW, then invert the image by going to Image > Adjust > Invert.
Go to Filter > Stylise > Wind, and set the wind to From the right. Now you’re back to rotating your image again so go to Image > Rotate Canvas > 90 CCW.
Next, go to Image > Mode > RBG Colour, then Image > Adjustments > Hue/Saturation, and set the Hue to 225, the Saturation to 35 and the Lightness to none. Check the Colourise box and click Ok. Alternatively, adjust the colour as you wish by using my colourising tutorial.
Finally, save your image!
