It was September, year 2008, when we were surprised by an intriguing seminar hosted by Coffee Beanyard. Why intriguing? It is because it cost too muchyet it's just a coffee classroom seminar. Even we're unwilling to attend, we have no choice because it's compulsory. At the middle of that seminar, we realized that our payment is worth it. Here's a video of some designs our speaker taught us. And these are totally AWESOME.
