About This Design

hadamard64 T-Shirt

hadamard64 T-Shirt

This design is a visual representation of a mathematical object called a Hadamard matrix. (In the mathematical form, each white square is 1, and each black square is -1.) What is special (almost magical) about this pattern is that if you compare any two rows (that is, compare squares in corresponding positions), exactly half of the squares will be the same colour and exactly half will be opposite in colour. The same can be said of any two columns. Try it! (Mathematicians would say that any two rows, or any two columns, have zero correlation.) A few other observations: The Nth row has the same sequence as the Nth column. The first (top-most) row and the first (left-most) row are all white, but all other rows and columns are exactly half white and half black. Divide the matrix in quarters (half horizontally and half vertically): Three of the quarters are identical and the fourth quarter is the negative of the others. The quarters of these quarters follow the same pattern. (etc.) Can you find and describe other patterns? The upper-left quarter is a smaller Hadamard matrix. (etc.)

Delivery was just on the last day's of Delivery estimate,but within E.T.A just,So No complaints.Cotton is of Good Quality.Fit is Prerfect to 5% bigger. Very Good but Not perfect,but at Ordering would have taken V.Good AnyDay!!Only Slight thing(as NO Bleeding,NO Smudging or ANY probs with acctual writing,is that the Red/Black and T-Shirt Colour isn't as Bold/Bright as in picture.BUT! When i took pic's of T-Shirt on my Phone for this review,it again looked like Bolder/Brighter Colours by 10-15% than in reality.......

I really like the design but I'm not sure the white base really took as you can see pink through her fur/bikini. So that was a little disappointing. That's more on the printing side though than the actual design, the design is really great, Cutey Bunny looks so beautiful! If you're thinking of getting this then I'd say just go for a white T-shirt and you should be fine.
