Friends of mine have sent me these transparent billboards for Sony PSP they spotted online. Have you had the chance to see them live anywhere in your neighborhood? Even though they work only from certain point of view, I think they are marvelous, and catch consumers attention. We really didn’t have much transparent illusions lately, so this comes refreshing. What kind of illusions you like the most? Which type should I post next? You tell me, and I’ll deliver. It really took me by surprise to see over 150 comments for yesterday’s post. You are doing great job, please keep it so!
