My old computer stopped "talking" to me and went to computer heaven.  Technology has sure changed since I bought that one!  I got an all-in-one HP Touchsmart.
My photos were all on an external hard drive and somewhere along the way I realized it would be a good idea to keep folders for things I added on to photoshop, but I still had/have a lot of stuff to move onto the new one.  I installed the extra fonts that I like, and just started looking at the filters.  I installed Tri-moon's impressionist filter.  It works with CS5, but not with CS5 64-bit.  That's OK because I have them both installed on the new computer.
So here's that same daffodil pic done with the impressionist filter.
Now I have to figure out how to add the rest of the stuff I've bought -- like the Topaz filters.
