I found this book cover on Amazon and it immediately caught my attention. To me, I think that this is a very interesting book cover. Unlike most book covers, this cover has somewhat of a “double title” and the style of the lettering is very unconventional from many other books. The cover of this book is directed towards grabbing the attention of the potential reader with unique styling and visual cues. The title reads “Things to Do and Make in the Fourth Dimension” but it is crossed out by a a scrawly text that serves as a subtitle. Having the actual title crossed out by the subtitle is a very unique method of presenting this information. The scrawly handwriting has a playful nature to it that represents a mathematician’s “sandbox” which is explored in the book. The object constructed by the tape measures is a tesseract which is essentially a 3D representation of a 4D cube. For those that did not know previously what a tesseract is, the object is interesting just by itself through visual appeal as it is not a common household object that we might see from everyday life. The use of tape measures instead of a regular material such as wood to construct the object once again represents the playful nature of the mathematician’s “sandbox.” I refer to the book as a “sandbox” partly because of the appropriately named title, which suggests that there are many interesting things to do in the 4th dimension which really captures people’s attention and sparks their curiosity in the book. Everything about this book cover is meant to generate curiosity; it’s playful nature just might cause enough interest in people take a second look at the cover and to read through the book itself.
