I am creating an easy digital painting creator with the focus on using my pre-made assets.

It's still very early days and it has only a few assets now, but over the next couple of years I am hoping to add hundreds more.

You can try it at http://www.artistcanvas.org

(Works best in chrome or firefox or similar based browser, and needs javascript turned on. No plugins required )

And it uses HTML5, so if it does not work for you get the latest version of the browser.

Google link text.

I am slowly adding things and intend to improve things, so a lot there is just very basic at the moment.

You can now however do this:
BTW, thanks BFett for the tip, I have now corrected it.

Interesting, but for now it does not work well on my iPad/Safari: i can draw (black circles) somehow 3-4cm above my finger, and I cannot draw/add any of your pre-made art.
Just for your information...

It does not work properly on a touch screen device.
I would have to incorporate quite a few more changes for that to work well which I shall do but not for a while as I would like to increase the content first. Also many touch screen devices are not running this fast enough yet. It works well on a quad core PC or higher anything less it is a bit slow. Which is more the fault of the browsers than the coding I have done I think.
