## Anime projects

Image 2 represents another category of Scratch projects commonly seen on the Scratch web site. Many of the scratchers create the characters forwhat amounts to animated comic strips often referred to as anime . Sometimes the characters are used to tell a story and sometimes the programmers/authors/artists are content to simply draw and display the characters.Sometimes I read about two scratchers getting together with one doing the art work and the other doing the animation programming.

Image 2 shows an educational animation with instructions on how to draw the head of an anime character. Click here to view thisproject online in your browser. If you run the project and click on the green button labeled next in the upper-left corner several times in succession, the program will cycle through thesteps involved in drawing a head.

I described pandalecteur earlier as a serious artist . In the same vein, I would describe dialga who created the project shown in Image 2 as an anime artist . I'm not discrediting or indicating a preference for either artist. I am simply recognizing the different viewpoints of thetwo. Click here to view more of dialga's creations.

## Game projects

As you may have guessed, many scratchers like to create games. Most of them are 2D games such as the Marble Racer game by jamie shown in Image 3 . The object of the game is to use the arrow keys to cause the marble to roll all the way around the track withoutbeing slowed down by rolling onto the grass. Click here to view the project online.

## 3D games

Although the mathematics involved are probably too advanced for most scratchers, a few scratchers push the envelope and attempt to make 3D games. Myobservation so far is that most of the 3D games that they make are so slow as to be extremely boring. Nonetheless, working on a 3D game in Scratch is avery educational process since Scratch doesn't provide any built-in support for doing 3D projections other than providing the necessary trigonometric functions.

## A pseudo-3D animation

Image 4 shows a pseudo-3D animation of my own design. In this project, the walking sprite follows the mouse pointer. Various trickswere employed to create an illusion of perspective in order to create an illusion of 3D. Click here to view the project in your browser.

## An animated story

Image 5 shows an animated story named Day Dream by cremeglace . In this project, the main character has a dream that goes through several scenesbefore reaching the end of the dream. The project includes music and dancing sprites. Click here to view the project in your browser.

## The tip of the iceberg

These five example projects are simply the tip of the iceberg in terms of the different purposes for which scratchers create projects. If you canimagine it in an animated computer program, some scratcher has probably alreadytried to do it.

Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
Joe
anyone know any internet site where one can find nanotechnology papers?
research.net
kanaga
sciencedirect big data base
Ernesto
Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well
Maciej
Abigail
for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
or in general
Ebrahim
in general
s.
Graphene has a hexagonal structure
tahir
On having this app for quite a bit time, Haven't realised there's a chat room in it.
Cied
what is biological synthesis of nanoparticles
how did you get the value of 2000N.What calculations are needed to arrive at it
