It has been said before and we can repeat the same again – art has no boundaries and inspiration for art can come from anywhere. That is why it is not impossible to think of artistic possibilities coming out of something as mundane as your cup of coffee. Why not think of coffee foam as art as artistic examples have been known to be inspired by many things? That is why there are so many pictures of painted rocks for inspiration.
Alternatively, in case you want your art inspiration to be in smaller doses, then you can look at mini sculptures to keep you inspired. Some artworks last for a long time while some are transient but bring much pleasure to the person who gazes upon them nevertheless. These creative chalk art examples are one of the art forms that one may not be able to preserve for a long time.
