My favorite designs are the boombox and the abstract-looking one in the bottom middle
If you're adding components to the boombox, try to make it functional. Also, if you're doing the boombox, try to add some detail to the facade.
I think this design has enough complexity to be intresting to build, BUT if things get overwhelming, it could be easily simplified. My design will be using a lot of additions, such as buttons, screens, and a charging port; it will be a challenge to properly wire and code for them all.
I've kept the main identity of the speaker mostly the same; however, I have made a few small changes. For example, the phone holder and the CD player have been removed, and plans are also in the works to incorporate more of a pattern onto the face of the speaker. There are additionally two new speakers.
