Voice to Image Function
I found a post about zefrank’s voice drawing tool on Drawn. I am a sucker for playing around with these kind of things. (See post on Text2Image) To vocally draw, all you need is a mic. Check out the Drawn post for a preview. There’s a video of one of their guys messing around with it. Again, teachers, this is an opportunity to play around with the idea of function without having to use real-valued examples.

Binary Ops
I’ve been catching up on some feeds and found two great examples of visual binary operations on Drawn. The above is from Christoph Niemann’s I Confess. It purports to explain how to use the two main elements of any news story and their accompanying visual metaphors to get a 90% acceptance rate on sketch proposals. I have no idea if this works, but love the clever graphic. The video below is Austin Kleon’s charming How to Draw Faces.

text2image fun!
text2image is a fun (and probably totally useless) way to transform any text into an image. Above, you are seeing the visual rendering of ‘yofx’. I was thinking that this might be an interesting way for students to conceptualize a function. I hate to say it, but sometimes real-valued functions get boring. Another plus is that we don’t actually know how the text gets transformed. Discovering properties of the function by playing around could make for an interesting exercise for students. Is it one-to-one, does an all-caps text string map the same as a lowercase string, what does the domain look like, is there a character limit, are all questions students might generate. I picked this up from Information Aesthetics. Check out that post. There are also some links at the bottom of their post to similar trans-medium mappings.
