A few nice photo effects images I found:
Howth Cliffs
Image by matttrent
Technically an infrared filter, not ND, but the effect is the same.
Waterfall 2- Aviary edit
Image by Phototropy
Second image edited with effects
not bad I think
Have you tried it?
P.s. I know you can do all this better in various installable programmes or apps but its convenient on a netbook on the go.
