Boiling the soft egg aka Webcam Stories
If you came here after seeing my FOTB talk – that's great! Thank you! Make sure you've seen the [Black or White vs Machine Vision mash-up](http://play.blog2t.net/files/black-or-white/) first. Then head to the HiSlope GitHub repo to [download/fork the HiSlope toolkit](http://github.com/og2t/HiSlope) and have fun. **Yes, HiSlope is opensource!** I am going to add more examples, couple of cool and previously unreleased Pixel Bender filters and more tutorials/documentation soon, so make sure you [follow me on Twitter @blog2t](http://twitter.com/blog2t). Please send comments and feedback, I'd really like to hear from you! Any Q&As - catch me at the conference.

Flash Bokeh
Sometimes your best efforts to convince clients to originality end up in the trash... but on the other hand there is nothing wrong with it – just shake the dust off and share. This time it's the colourful realtime [bokeh](http://en.wikipedia.org/wiki/Bokeh "Bokeh on Wikipedia") effect inspired by this [tutorial](http://abduzeedo.com/colorful-bokeh-effect-pixelmator "Bokeh effect in Pixelmator") and programmed for [tictoc](http://tictocfamily.com) as a proof-of-concept demo. __Click the image above to preview.__ Due to expensive alpha and blending processing it may slow down your browser/computer a bit. I've tried two approaches there: 1. Adding and removing circles to the display list (withcacheAsBitmap
turned on).
2. Drawing circles onto (transparent and non-transparent) bitmap using draw()
method.
Both methods eat similar processor time. Haven't tried using any GPU wmodes, not sure if that would help at all here, I'll leave it to you - the code is very simple and there's __a lot__ of room for improvements and optimisations.
Considering the recent [HTML5 vs Flash war](http://www.google.co.uk/search?q=HTML5+vs+Flash), the challenge is to code a similar effect using JS + HTML5's canvas and compare the speed – is anyone up for it?
Grab [the source](/files/bokeh/bokeh_demo.zip "Flash bokeh AS3 source") (AS3, Flash CS4 was used to tween the circle shapes but you could entirely use drawing API if needed) and enjoy!

Old skool TextField plasma (dithered)
I had a quick poke into FontStruct last nite, some useful features had been recently added to that awesome online block font editor. I found one of my previously designed fonts called [RUdigit?](http://fontstruct.fontshop.com/fontstructions/show/rudigit), it's pretty (experi)mental (check the pixel size, otherwise you won't get the idea). That reminded me of an old Flash AS1 experiment of mine, where I tried to use predefined character set to display various shades of grey. We used to do it a lot in the C64 demoscene days – nostalgia had kicked in and I quickly mocked up an AS3 version of that old triple sinus plasma code.TextField
™. It's pretty slow I must say but I didn't spend a second to optimise it. Maybe drawing a single character onto a bitmapData
or using copyPixels
would work faster? I might look into that again, most likely when the C64 nostalgia takes me over again sometime.
If you are new to this technique, have a sniff into the source. TTF font included. Enjoy.
