I found some more symbols that represent using Green technology. It shows how some are represented in the real world to get the message across. It makes you think how the symbols we create might want to be represented and where they will be seen.
I see logos all the time and think to myself I should redesign that for them because some logos out there are really bad. Here is a list of some logos that are pretty well known and were redone in think very effectively.
I found this diagram of how far a little extra money can go and thought it was pretty cool with how it represented the information. For example the color scheme was a slightly off green color but you can still tell it represents money. Also the color hierarchy helps with showing the more important information. The type also works well in the hierarchal way because the more important information is represented, so you don't have to read the smaller text and you will still understand the diagram.
I found this information design that uses color really well with having wine being its main topic. The type in these pieces work well because they add the needed information but don't detract from the main design. Also the visual hierarchy leads you down through the piece nicely.
