The two main ideas I have in my head are as followed.
If I do a map of myself, I'd either try and make it into a video so as to be like a travel channel type showing of myself. On this corner if my love for soccer and over there is his love for video games etc. I think it would be funny to do but I don't know if I have the time to work on something and have it look polished. This would be a good way to show the many different parts of myself and make it into an enjoyable thing to watch.
The other idea is some sort of t-shirt with quotes I find relating to self identity. They could be mine or other famous people. I'd make each quote into a different looking font as to make them each unique. This one would be easier to make but I'd have to make sure it doesn't look bad. This would let me say what I think and find others that go with what I'm saying.
I just hope there is a easy way to save all of this into a final portfolio later. How does one save a t-shirt he might want to wear?
