Back in 2016 I started to use a software called "Depthy"
You create a shadow light and dark and basically it will wiggle the picture.
Ima start posting them in a "posts" rather than have them in my Art portal, because I don't think they are good enough to be posted in my Main gallery.
I am treating Newgrounds as my main hub but also as my Archive. so if you want low quality tweened gifs Ima start just putting them here.
