Flashmob Public Art & Cheerful Crafting on a Whim

Guerrilla art is the creation of unauthorized public art in a spontaneous and secretive manner. Guerrilla gardening and guerrilla knitting (also called yarn bombing) are two other recognised forms of temporary public art. Although not entirely legal, guerrilla artworks are usually meant only to add interest and improve a public area for a short amount of time.

Guerrilla art is often also used for advertising and marketing (with permission) - an example of which is the guerrilla gardening by 'Adidas' shown below.

Flashmob art is where a group of people organize an event secretly amongst themselves and then carry out a particular action at the same pre-planned time. There are some examples of this below too.

I have compiled many of my favourite photos of fun public art, plus links to inspiring photo galleries and ideas. I hope you find this page interesting!

Guerilla Knitting

A Little Introduction

The Types Of Street Art

Guerrilla art exists in a variety of forms, including temporary sculptures, drawings, posters, freebies left in public areas, messages posted on walls, knitted or crocheted items and gardening work. A lot of the time the artworks are simply for artistic purposes, to raise a smile (awww), or to make a place looker prettier, and sometimes it is for catching someone's eye in order to advertise a business, scheme or brand.

Guerrilla gardening is usually for sprucing up a neglected area, and one form of this is...

Seed bombing: This is where bundles of soil and seeds - often called seed balls or grenades - are thrown into an area of land which is barren or bland, in order to add growth and color to make the area more attractive. The soil and seeds are compacted together into balls or compressed inside a bio-degradable outer layer.

Another popular idea is for crafters to either knit or crochet a jumper for a statue or some other fun object to put in a public place simply for temporary decoration and for good old-fashioned fun! This is referred to as...

Yarn bombing: Also called guerrilla knitting and yarnstorming, this activity is technically illegal (even though it is removable and harmless) so you have been warned! I've never heard of anyone being arrested for wrapping knitting around a tree though :)

Fun Art Books

Books like these ones are definitely the best way of browsing the best examples of guerrilla art in one place...and perhaps they will inspire you to create your own little pieces of public art to brighten up other people's days!

Rock Stacking


Stacking rocks and pebbles like this creates attractive sculptures, and you can try to make temporary art like this yourself on your next beach trip or hill climb, so other people can see and enjoy them too.

Flower Project


The 'Guerilla Flower Project' was an experiment about guerrilla marketing, treasure hunting & flowers. 130 paper flowers were hidden overnight in Villa Guardia, a little Italian town. Each flower had a card with a little nonsense rhyme, a web link and one of five different pieces of a treasure map attached. If you could find every part of the map, you were able to reach the treasure, hidden in the flower shop of the town.

Water & Broom Calligraphy



Guerilla knitting (sometimes referred to as 'yarn bombing' is where knitted sections of yarn are added to objects in public areas.

The tree shown above consists of sections knitted by only the local community and it took 4 hours to put up. It was installed for the Viva La Gong Festival in Wollingong (2009) and I love it!

Colorful Crossroads


This guerilla event started with brightly coloured paint being poured in front of cars whilst they waited at the traffic lights, and resulted in pretty and colourful tracks being made all over the crossroads. Don't worry too much though - the paint used was washable, organic and biodegradable!

It took place at Rosenthaler Platz in Berlin.

Guerilla Sculptures


This guerilla art sculpture appeared overnight in Gas Works Park in Seattle. The artwork consists of a gold-coloured male sculpture standing on the waterfront surrounded by sculptures of people emerging from shells. They are all made with papier-mache.

Morph Flashmob


This lovely guerrilla art installation was created by flashmobbers who brought along their own 'Morph' inspired clay creation and placed them outside the Tate Modern on the Southbank of the Thames, London. The event was organized to celebrate the work of Tony Hart (the creator of the 'Morph' character).

Fun Arty Ideas

Please remember that guerrilla art is not strictly legal and therefore trying these ideas in public is not advised and is at your own risk!

Really cool, like it a lot. I would love to see more subvertising going on in my city to make people stop and think, especially when made out of plants :)

I absolutely love your lens. What a great topic and full of inspiration. Thanks for taking the time to make it :)

Nancy Graham on May 26, 2011:

This is a very cool lens. It is inspiring. The yarned tree looks so wonderful and happy, but I wonder how it affects the tree's health. Despite that, love the concept and your lens is very well composed.

Thank you for this great lens! I love making and distributing guerrilla art. I highly recommend Keri Smith's book, The Guerrilla Art Kit.
