Those are awesome....
I guess my Photoshop version 6 is too old...
My filters menu goes: Artistic, Blur, Brush Strokes, Distort, Noise, Pixelate, Render, Sharpen, Sketch, Stylize, Texture, Video, Other
What verison Photoshop you using? I hear 7 was horrid (thats why I never upgraded), but hear the new CS is pretty nice...
