For the last 5 years, Massachusetts-based graphic artist David Laferriere has been drawing whimsical characters on his kids’ sandwich bags before packing them for lunch. Each drawing of the Sandwich Art series is made with Sharpie markers, then photographed and posted on flickr before David’s 13 and 15-year-old sons discover them at school.

French artist Thomas Lamadieu, also know as Roots Art, must really love looking at the sky, but for different reasons than you might think. Every time he looks up, Thomas sees a potential canvas where the building rooftops frame the sky. He photographs it and uses the odd sky shapes to create whimsical line drawings.

Seeing how popular his recent lion painting was, Hong Kong born artist Marc Allante decided to show the 25 years it took to get there. Starting with the portraits of his grandma (“oma”) and grandpa (“opa”), the stream ends with a fascinating colorful lion, drawn at the age of 25.

If you liked the marker-drawn murals by Charlotte Mann as a way to decorate your room, you’ll also love this like-minded German artist Heike Weber. Based in Cologne, she uses permanent markers to create mesmerizing floor and wall drawings which sometimes cover up to 5000 square ft. By carefully planning and controlling the white spaces between each line, Heike gives her drawings a 3D feeling. The space around the viewer may seem to be constantly swirling and floating, and you might find yourself losing the ground under your feet.

Adele Emersen used to present herself as a copywriter & concept designer in advertising, but now she’s probably more famous for her maternity leave hobby – photographing her children while they sleep and then adding some adorable details to the pictures. This summer she photographed her baby with an iPhone, and then sketched some activities on top of the pictures. Minimalistic and nicely child-like, they are exactly what you wanna see in your childhood album once you grow up. Some moms just don’t know what it means to get lazy or bored!

Even though Ramon Bruin has a degree in airbrushing, it’s his other skill that made our jaws drop. A Netherlands-based artist shows demonstrates how well he’s mastered the art of 3D illusions, all drawn by pencil. As he puts it, trying photo-realism was just another way for him to push his boundaries and add another technique to his portfolio.

Do you remember the amazing 3D Pencil Drawings by 17 Year Old Fredo we’ve shown you last year? Well, don’t be deceived, this is not another collection of his work. The sketches below are all drawn by the 21-year-old Nagai Hideyuki from Japan. Inspired by British 3D street artist Julian Beever, Hide uses the same projection technique called anamorphosis which allows to create 3D illusion when viewed from the correct angle.
