I had no intention of doing another app review so soon, but I discovered Percolator last night and I love it so much I had to share it Right Now.
Percolator is a fun photo app that turns your pictures into mosaic works of art.
You can really fine-tune the effects, and decide just how much of your original image you want to retain. I'm still figuring out what all the different settings do. I love this photo I took of my mother's friend on our last day in Africa, I'm not sure exactly what I did in Percolator, but it's just magical:
I love the creativity of this app, it makes me feel so artistic, even though its ridiculously easy. Of course there is a flickr group, with lots of interesting work being done in combination with other apps too.
The website shows the price is $2.99, but it's only $1.99 right now in the app store. I'm not sure how long that will last, so I'd get it quick! There's also an iPad version, which I can only imagine is downright amazing.
