I know its not an acutal problem but I found this demo http://cssdeck.com/labs/interactive-particle-logo
Can someone explain how draw png images on canvas with other objects?

In that example they are using a library called particle slider which takes an image and draws it in particles.
See http://particleslider.com/ for more details.
The exact method you want is here http://particleslider.com/documentation/api#ParticleSlider.getPixelFromImageData
Going into how to write the library from scratch is probably a bit to advanced for a stackoverflow question :)

Does anyone have a simple solution to extract frames from a gif using javascript?
I know some online tools like Ezgif and Gif-explode, but I'm wondering if this is also possible using just javascript?
For a client-side solution I'd recommend to have a look at libgif-js.
It allows to step to a specific frame in the GIF and you could then use the Canvas API to capture a single frame by drawing the image to the canvas and then getting the Data URL.

I wasn't sure if this question has already been asked before but I was wondering how you produce the interactive dotted text and the running tiger animation you see in the middle of the run4tiger website?

Any information would be appreciated.
They are using canvas elements to achieve this.
The canvas will catch the mouse over events and then react accordingly.
The loading tiger screen was drawn using SVG.
