Yesterday I blogged about one of our gallery exhibits. Read the article. Even though it's an Autodesk Gallery exhibit, I have not had any personal contact with anyone from the company. I just know the product from the exhibit. Well to put my money where my mouth is, I bought one. I simply went to their website and ordered it: It arrived a few Sundays ago. I anxiously opened it.
