Her most popular filter is Color Forest this one make the user look like a painting and has some particles (leafs) flying by. The second most popular filter is Bunny Twins, this len add bunny ears and a ribbon. After this too the most popular effect is the PuppyLove this one is perfect too use with you dog, it will add some little hand, holding flowers and the eyes of you dog or other pet will pop with some small cartoon hearts.
diwu did some tests with augmented reality lens with the effect Floating Glass, this one will generate some stained glass, coloured glass, that are been applied almost exclusively to the windows of churches and other significant religious buildings.
