Download this project!
Download the one sprite and one script of "Persistence of visio…" and open it in Scratch Project Notes
A quick project which shows how persistence of vision can trick our minds into thinking we are seeing things...in this case a word. In reality, all you are seeing is a line of black dots moving across the screen. Probably won't work online, but I hope it does. The word appears to flicker, cause it is being drawn in. I made this for fun :P

Lol. You think up the greatest stuff. Keep it up! =)
Thanks! I made this one for fun! You can improve the speed a little bit more, but it is going to fast to register beyond that, so it is hard to do in Scratch!
dude.wow.
lol, a better example of POV is my project Stars.
i see HI
Hi!
i see hi or hic
i see hi
And you are correct!
(view all replies)my eyes seem to be to fast for it,even when downloaded!
Squint a bit, that might help!
could this cause epileptic fits? it flashes quite alot
Presumably no, because it is not flashing quickly enough, and it is just a few dots as opposed to a whole screen.
>> I see HIC
Close, just without the C
oh i see it now. it says hi. YESSSSS!!! i did it.
U got it lol!
Fun
cool, i saw it says hi...lol
I had to lean back and look at it from more of a distance before i saw it. seriously how do you think of such random ideas for projects.
I have no idea. A better example of persistence of vision is my latest project.
cool cheak out my projets will you help them???????
Dude, you spaced the letters too far apart... These things need to be closer together to work well...
Sorry, its close enough though. You can mostly see it. For a better demo, look at my most recent project. That one works way better!
lol the word says hi
Hi!
Hi Dan01!
(view all replies)Yeah I know what you mean..... But still, It takes alot to make a simple program when you know next to nothing about the programming language...... VB is dead simple to learn, Java takwes a while, but squeak...... I dont know how long........... lol
Cool, I'm having trouble opening the Source File..... Anyway, if VB and Squeak are that similar, with booleans and stuff like that then shelling stuff and reading files in scratch hopefully wont be 2 hard.... and if so then scratch will become a mad frenzie of many-another thing....... Looking into it now!
Following a logical pattern, that %n is an opening. A numerical opening, hence the n. If it is %b instead, it is a boolean opening.
Actually you probably know more about Squeak syntax than you think. For example, in VB = means "is assigned the value of" unless it is in an if statement. In Squeak, _ means the same thing. Another thing which makes it relatively simple is that if you know English, you know most of the syntax already. In the sourcecode, I figured out that whatever is in the single quotes is how the block will appear because I recognized 'wait %n secs' to be the wait block.
Dude, u must be a serious programmer... I mean, I know alot of Java and VB but ur knowledge of Squeak (although most of it was Jens) Isn't bad at all........
Nope! When I first started Squeak I thought it was insanely hard. But after a while, it started to make sense. It became very easy. I know almost nothing of Java (I can make words but that it about it, I used the Jcoder, maybe if I used NetBeans or Greenfoot I would have been more successful) and VB is kinda simple, albeit the things you can make are complex. Most of what I know of Squeak came from trial and error.
Actually all computer images I think are shown this way(correct me if I'm wrong) I think they're just flickering dots flickering too fast for us to tell.
Yes, but not too fast for a camera to tell :P thats why they flicker on tv unless the images are simulated.

At first I though it said "Fitch" as in "Abercrombie & Fitch". Then I read ferret10's comment and relized it said "hi". neat project.
Thanks lol! It can be kinda hard to see, but you have to squint a bit.
it says hi
Very cleaver. Have you tried it with smaller dots and a smaller area covered in hopes of improved speed and less flicker? Just a thought:)
I bet it will! Good luck!
Thanks! Actually, size does not matter. Motion does not matter. Paddle2See tested it out as seperate backgrounds, and it was still flickering.
(view all replies)i think it say hi!
Yup, it does!
(view all replies)HI! It displays it on the webpage just fine. Anyways, I've been working on a simple polygon filler. I have it to an almost finished state, but when it gets to the top of the polygon, it flies out of it! I'll have to work on that... Also, I still need it to be able to locate the lowest point on the polygon for it to start if this were to become something like a 3d raycaster/renderer, a simple 3d filled-in cube, ect. Also, I need to work on the speed quite a bit.
Sure! Lemme know how that goes :p
(view all replies)Raycasters do not involve filling of shapes, just drawing stuff based on shapes. Good luck with that!
(view all replies)Hi!
Hi!
(view all replies)And That is what i am seeing right now a line of dots moving across the screen
Well, as I said, that is really all it is. If you try it offline, it actually runs a bit faster.
that is all words are...lines and squiggles that amazingly convay a vat array of infomation.
*vast
nice
whats the word?i have scratch,but i'm at my grampas,so i can't see it.
It says HI lol!
(view all replies)I'm at my grampa's too. I downloaded scratch and he didn't care.
(view all replies)Cool! I have a whirly toy with leds that spells things out that works just like this! This is a little hard to read on my laptop...maybe it's a bit too slow?
I did all I could to speed it up. This is the fastest it goes.
(view all replies)interesting. Thanks for making it.
Cool! You have very creative projects. :D
Thank you!
HI! That's awesome!
To tell you the truth, I have no idea. I come up with most of my ideas right before I go to bed, in the shower, or when I am horribly tired/bored. Thanks!
(view all replies)Thanks! I am glad to see that it works online (^_^)
