Oldschool41 : Having a blood sugar meter on a phone is cool . I want to have that too .
Eddy88 : A magical T-shirt ? 

Ktanaqui : Maybe... Sounds pretty difficult to make with Technology... So, yeah.

Magical T-shirt.

Eddy88 :
Yeah, that's basically what I'm wanting. Except, I want it for the Nintendo 64.

Oldschool41 :
Wouldn't it need to prick you to do that?

Oldschool41 :

Well, then you'd have to invent your own phone that had a pricker attachment so that it could prick people for the blood that it needed to complete the test! Maybe that should be an item idea too?

Oldschool41 :

Wouldn't adding a needle still call for creating a whole new phone? I doubt that Apple would allow you to modify theirs... and yea, it is a stiff market. One which I basically avoid. XD

Oldschool41 :

That would probably work better than just creating the app or creating an entire phone with the ability. Creating the app means that somebody else would have to create the technology... You could try getting statistics first?

I would create something that could create oil without waiting for millions of year, because oil is running out right now. Oil is important, because it is use to make a lot of things.

Mobouis1 :

Maybe it would be better to create a substance that is cleaner and replaces oil entirely? Oil is bad for our environment to begin with. (For what it's being used for anyhow.) A cleaner substance would be nice :3

Ktanaqui : That's an amazing idea. I would love to have adapters to plug in to my laptop for all the retro games. Any of the systems would be cool to use.

warmaker : That is a really smart idea. It would help out so many more people and they'd have clean water anytime they wanted it.

iSPY! : Haha, that reminds me of the movie Multiplicity. I'd use my clones to confuse people. Make them think I am in one place and then I'd call them on the phone just to flip them out.

And the idea about trying to create a cleaner substance that would replace oil is a really good idea. Unfortunately I can't think of any good ones right now, but if I do I'll even post it in a later reply. Great ideas everyone?

I would invent a machine that would promote understanding between people, it would give people the ability to understand why someone is the way they are, Help people to grow and understand others, This way instead of judging people we would have a means to know what motivates the person and promote a compromise. I would call my invention Empathy. As it would help create that between people. 

If "anything" includes items that are impossible, I would create a Star Trek "replicator" which can be used to produce things like water, food, and clothing from less important materials like sand.

A way to desalinize water quickly, cleanly, and efficiently. Oh, and the water would actually taste good!
There, I solved the world's water problems. And now we can focus on creating fusion!

If I could any object in the world I would create an object that could function as any thing and every thing due to the fact that I am not a good decision maker so I would want to have an item to help people, to entertain people, and to teach people. This could be a conjured tablet from a cloud and needed to be made with a special tool because you need to cut a cloud and then you could just type in the search bar and the micro printer in the bottom of the tablet would create the object. A cool feature would be is to add a pen to it and with the pen you could draw on the screen and then type about what you would want the object to look like and to act like. Another feature could be the ability to create a description of a perfect animal, creature, monster, or living person to be part of your family or your friend or your crush. The data code of this machine would be something like this 1 2 1 2 1 4 1 3 4 5 2 5 3 3 5  32 2 4 2 3 5 3 3 5 6 3 4  6 4 4 6 6 4 6 4 5 4 6   8 1 4 2 8 2  5 4 58 2 4 65 8  4 5 Just to name one of the first lines. As you can see I could talk about this all day but I am going to wrap it up here.

Personally, if I could have a gadget, I'd want some sort of bracelet or, pendent that would monitor the vitals of someone.

You see I have a pregnant wife going through a complicated pregnancy, and while I'm over joyed with the idea of a father, I am deeply worried about what might happen to her.

So if I had a gadget I'd call it something like 'Health Guard' or 'Guardian Monitor" or something like that. So I'd know she'd be safe/
