The word "pixel" is immediately recognized. Because it is such a graphic word to begin with, I believe that an icon that purposely goes against what the audience expects will make more impact. This icon is bold and memorable. I believe that it can also stand alone.
This is the "runner" I've been using for the concept of your design. I think you can create some very interesting animations with the different elements that I used to create the runner. One idea I keep thinking about is having each element fly onto the screen individually so that eventually, the runner emerges. After that, the name of your company can fade in. I think that would be very cool and dynamic.
Hey there - here is a revision using a different typestyle. Please let me know if you would like to see any specific revisions to the design. Thank you!
