These are some amazing vector portraits. Awe-inspiring in some cases. Some are so realistic I actually have to drop them because I can't confirm whether they are not photos. You'll be able to see some insane wire mesh and gradient work going on.
Yarn Bombing is a type of graffiti or street art that involves fixing yarns onto public structures. It's a non-permanent form of graffiti and can be easily removed. People would knit up a big piece of yarn and bring it to the location before attaching them together. For bigger objects like cars, several pieces of smaller yarn are required.
The Falles is an annual celebration held in commemoration in Valencia, Spain. Each year, artists would create huge puppets or dolls (aka ninots in Valencian) of animated characters. The place looks like Disney land with the characters populating the streets, except they aren't the copyrighted characters. The displays are temporary and are burnt as huge bonfires at the end.
