We all have three types of color photoreceptive cells in the back of our eyes (the retina) – which are often called the red, green, and blue “cones.” We are trichromats. Each of these ‘flavors’ of cone is sensitive to a particular range of colors of the spectrum. And usually when we perceive a color, it is the result of a combination of signals from more than one flavor of cone. For example, seeing “orange” is the result of a moderate signal from a green cone and a stronger signal from a red cone. And we are able to distinguish the range of orange hues from each other by the different strengths of green and red cone signals that each orange hue generates (darker orange would have a stronger red signal, etc).
Can you see any symbols or letters in these circles?
But how many shades can you see here? Count them!
*If you see more than 33 shades, you are a tetrachromat, like bees, and have 4 types of cones (in the purple/blue, green, red plus yellow area). You are irritated by yellow, so this color will be nowhere to be found in your wardrobe. 25% of the population is tetrachromat.*If you see more than 39 color nuances: come on, you are making up things! There are only 39 different colors in the test and probably only 35 are properly translated by your computer screen anyway :)
But eyes change over time. You may have heard that digital cameras can be by removing the IR filter found inside, but did you now that something similar can be done with the human eye? People who have aphakia, or the absence of the lens on the eye, have reported the ability to see ultraviolet wavelengths. Claude Monet was one such person:

"I drew the duck blue, because I've never seen a blue duck before,
and to be honest with you, I wanted to see a blue duck."
“Imagination is more important than knowledge.
For knowledge is limited to all we now know and understand...
...while imagination embraces the entire world,
and all there ever will be to know and understand.”

“Manners do matter, but I’d prefer that she not be too sophisticated at a young age.
When we’re making art, I try not to show her any techniques.
If she wants to draw a purple frog with curly legs, I don’t correct her.
That’s her imagination
and I don’t want to damage that part
of her nature.”

"I thought that after this type of connection, we would be friends for a very long time. When the airplane landed, imagine my surprise when, as I reached for a piece of paper in order to write down my phone number, my new friend stood up and with a friendly wave of his hand said, "Nice to meet you! Have a great trip!" And that was it. I never saw him again. I felt he had purposely tricked me into opening up when he had no intention of following through on the relationship he had instigated."
The difference between American and Russian cultures here can be described as peach and coconut models of personal interaction.
In peach cultures like those in the United States or Brazil, to name a couple, people tend to be friendly ("soft") with others they have just met. They smile frequently at strangers, move quickly to first-name usage, share information about themselves, and ask personal questions of those they hardly know. But after a little friendly interaction with a peach person, you may suddenly get to the hardshell of the pit where the peach protects his real self. In these cultures, friendliness does not equal friendship.
In coconut cultures such as France, Germany, or Russia, people are more closed (like the tough shell of a coconut) with those they don't have friendships with. They rarely smile at strangers, ask casual acquaintances personal questions, or offer personal information to those they don't know intimately. It takes a while to get through the initial hard shell, but as you do, people will become gradually warmer and friendlier. While relationships are built up slowly, they tend to last longer.

"How long does it take to master a craft? How about 80 years? Because 109-year-old Australian Alfred Date has been knitting since the 1930s and his latest/most famous endeavor was making mini sweaters… for endangered penguins!
Back in 2013, Victoria’s Phillip Island Penguin Foundation asked for volunteers to make sweaters for the rare “little penguins.” Alfie, who has yet to learn to say no, pitched in.

that you are
one of a kind.
that if there weren't any need for you
in all your uniqueness
to be on this earth,
be here in the first place.
And never forget,
no matter how overwhelming
life's challenges and problems
that one person can make a difference
in the world.
In fact, it is always because of one person
that all the changes
in the world come about.

In geometry, the golden angle is the smaller of the two angles created by sectioning the circumference of a circle according to the golden section; that is, into two arcs such that the ratio of the length of the larger arc to the length of the smaller arc is the same as the ratio of the full circumference to the length of the larger arc.
The infinite blooming effect is achieved by spinning the sculpture and photographing it with a camera with a fast shutter speed.

"If my life was a book
and I were the author
how would I want the story to go..?"
The obstacles on our tracks can stop us.... or force us to be creative.
They shouldn't disable us, but enable us - to believe in the possibilities. Our imaginations can be used as tools for breaking through borders. Because in our minds we can do anything and be anything. Following dreams and facing our fears head on is what allows us to live beyond limits.
Limitations force us to go further and ignite the change we so dearly wish for. Sometimes innovation only appears to us because of our borders, and comes about when we have taken that step beyond. It's not about breaking down borders, it's about pushing off of them and see what amazing places lie beyond.
Borders is where the imagination, and the story, begins..
