We are big fans of wall decals because they are the perfect decor solution for renters or anyone looking for a temporary update to a bland space. From classic movies to abstract electronics, these whimsical wall graphics are designed to appeal to the geek in all of us, and would certainly add a touch of fun to any space. They would also look great adorning a plain desk or bookcase. Unsurprisingly, several of our favorites come from sellers on Etsy.
