I recently hit a wall during a project and I was looking for inspiration as well as just an outlet for creativity when I stumbled across this website, Thinkdesignblog.com. I was impressed with the diversity of designs, mediums, artists and "freebees" they had. The first page has several different "inspiration" posts for prints, graphic design and web design, there are also artist interviews and some some fun textures that you can download. I struggle with finding an interesting textures but I was able to find a few that I liked and will be able to use in the future whether it is for graphic design or photography.
Simply flipping through the different posts help relieve the creative block I had and it also helped bring about different ideas that what I had not previously considered. I think that it is a neat little tool for remembering all the design options out there, or at least a pleasant break from a current project.
(P.S. Though there are some cool stuff on the page face, the goodies are in the archives so be sure to browse there!)
