Help on this effect.

Can someone tell me how to get a border like this on my icons, or maybe direct me to a tutorial I missed? I dont know what its called, so I cant look in the memories (I have been looking things up in the memories for a week and have yet to run across it along the way). Also, Im using PSP7


This icon belongs to grissom (made by _facade)

Also if someone could help me with these, tell me what effects theyre called, or direct me to a tutorial, Id appreciate it...
This style with the lines (kawai_rosh)
How does it slant? (exhero).

Thank you!
