Typography Explosion

This is the most interesting piece of typography I have ever seen! It is very tastefully done and the color spectrum in is very clear and bright. The way you placed the colors works so well at describing a color wheel. You see every color combination in a wonderful explosion. When I look at this piece I see it as being a great cover for a book teaching typography. What I can't tell though is if you did this piece by hand or if you did it digitally on your computer. Or both. I like that you can't tell though because typography can be done in either medium and it takes much skill to get each letter exactly right. The splatter effect as well looks so uniquely arranged that I thought only spontaneous brush splatters could do that! Congratulations on such a wonderful piece!
