I like how you are playing with the letterform in #19, have any other ideas for this? something a little more 'dynamic'. The current one is a little too boxy.
Thank you for your use of pixels in #79 - but I want to avoid using 'DDM' unless it is an abstract lettermark. Try doing it as a 'wordmark' with using pixels.
Think of it like an animation where the pixels are flying in from the left forming the letters on the right first ('ynamic'). The frame we are looking at all the letters are 'formed' except the 'D' in dynamic, which is only mostly formed (can still see the pixels coming in, forming the left side of the letter 'D').
