Here are some of the good designs I see floating around on the web.
This is by Tang Yau Hoong and he did multiple pieces using negative space such as this one. It's clever and I just enjoyed looking at this piece.
This is the logo rebranding for OCAD University, and I thought it was very interesting how they used this logo. What I like about this logo is that it is simple and very flexible on how you can use it. The size of the squares are consistent, as far as placement and what goes inside the squares can depend on where they use the logo. Just as an example, they use this logo for their student ID cards and inside the largest square they would place the photo of the student.
I really love the texture and how the artist used the typography to show the ocean waves. The image and the text go really well together, very clever also.
Package design Salih Kucuaga.
And some bad - decent ones.
This logo seems to be a little vague and droopy. Just by looking quickly, the d's can look like g's with the bottom part coming down. Not too memorable, and I feel like it can be refined a bit more as far as readability.
