I wish for my computer to become the best, most efficient, and most powerful computer on the market, while still allowing me to run my system properly, and without deleting any of my data.

Your computer become just that, the best computer ever to grace the realm of man. At midnight a week after your wish is granted, The nerds come together and plot to kill you with their ray guns and bladeguns.
You are violently nerded to death and your computer is stolen. Have fun roaming the world as a spirit.

I wish for beavers.

Wait, I'm a tree...
I wish beavers won't eat me.

They don't. Some woodpeckers come along and do the job.

I wish I was perfect at art, and I could make anything I wanted perfectly.

I wish I was perfect at art, and I could make anything I wanted perfectly.

Your art is brilliantly perfect, so much so that it comes to life and proceeds to enslave humanity, making you their muffin delivery truck driver.

I wish for compete knowledge of Objective-C and JavaScript.

[Aelcalan]

You have complete knowledge of Objective-C and JavaScript, but a new language is created that renders all previous programming languages obsolete.

I wish for a Reality Marble. (This one's a little obscure, so it wouldn't surprise me if nobody who posts in this thread knows what I'm talking about. )

[LeafWarrior254]

Googled it, obviously.

Spoiler:

The concept of a Reality Marble (固有結界, koyuu kekkai?, lit. innate bounded field) is having one's inner world materialized and projected onto reality following the World Egg (世界卵, Sekai tamago?) theory. Generally, it is used to refer to the alien common sense of demons (悪魔の持つ異界常識, akuma no motsu ikai joushiki?) in that it is how demons perceive reality and how Reality Marbles themselves are the natural abilities of demons and elementals. It is possible for humans to achieve this as an innate Bounded Field, though generally only in the cases of the powerful beings like The Twenty-seven Dead Apostle Ancestors and the greatest of magi who have spent years upon years researching. This ability is a similar and dissimilar method of "world creation" to Marble Phantasm, but rather than reshaping the world at their will, Reality Marbles allows only for the creation of a set world that defines the practitioner. They force all things to obey their rules, but it is limited only to that one pattern. It can be said that they can surpass Marble Phantasms at the same time, as they are capable of affecting things not of nature.[1]
It is a magecraft that comes close to being real magic, and as a taboo among taboos and mystery among mysteries, it is one of the pinnacles for a magus for which research has has been banned by the Mage's Association.[2] Those that do have a Reality Marble would inevitably earn a Sealing Designation if discovered due to its nature as a unique magical ability that cannot be acquired through study and does not pass on to one's descendants.[3] Obtaining a Reality Marble is not something every magus can achieve through research. Caster, far above all modern magi, cannot utilize one, but she could construct "another world" of the same scale with enough time and expenses.[4] Areas that are full of grudges, filled with remnants of strong regrets, are like Reality Marbles to spirits.[5]

I just skimmed, but I'm guessing you want to make another world... (?)
Granted.

I wish I had a donkey (***As in the animal >_>)

[Aelcalan]

You're supposed to twist the wish.
You have a donkey, but it doesn't like you, and promptly demonstrates the origins of the phrase "kicks like a mule."

A Reality Marble is SORT OF like a world, but I guess the term "pocket dimension temporarily created by superimposing one's 'self' over reality" would be one of the more concise explanations. We can just leave that one open for anybody that happens to have a good idea for it.

I wish orphans each had a tasty, fresh cookie of their favourite kind.

[bleush38p]

...aaand the orphans learn what girl scout cookies are actually made of and are thrown in jail for cannibalism.
I wish for said orphans to be bailed out of jail by their new adoptive parents.

the orphans are bailed. unfortunately, the parents decide that they're just not worth all the trouble, and, the orphans are tossed out onto the street.

He forgot to make a wish, so I will. I wish for all the cats in the world in a basket, every one wearing a bow tie. And I get to hug each and every one. <3

Yeah, the basket implodes on itself from the magnitude of cat memes that would bring. I wish for some more blood orange juice :I
