tumblr
I have a Processing sketch that I'd like to embed on my Tumblr. I've followed the instructions on this post for doing so, but all I get is an empty canvas and my script showing up as text.
I definitely have the required code they mention in my blog's header tags and have enabled plaintext/HTML as my text-editor. My code matches their format and I stripped all the returns out of the Processing sketch – is there some Tumblr-magic I've neglected, or is there an easier way of doing this?
I think you misinterpret what the user interface is saying.
There are two options in the video interface.
You want option 1. If you want to add some text you can use the caption.
Another way to do this will be a regular "Add a Text" Post
From there you can use html and YouTube embed option (using the share link at the bottom of a YouTube video) to place it where ever you wish.
Example
<p>Go for text</p>
<iframe width="560" height="345" src="http://www.youtube.com/embed/IwX3FdwMCUs" frameborder="0"></iframe>
<p>And here goes the rest.</p>
Include the following code:
{block:HasTags}
{block:Tags}
<a class="tag" href="{TagURL}">{Tag}</a>
{/block:Tags}
{/block:HasTags}
in the block for each type of post. So you will have this seven times: in {block:Text}, in {block:Audio}, etc.
Put this right before the closing of the block (so right before {/block:Text}, for example) to have the tags show up at the end of the post.
Tumblr provides some documentation on this here.

Same problem! What worked for me was to put a div at the beginning (before canvas...) and a /div at the end (after /script) when you are in the html editor.
Or maybe you could try with this "tumbleryfier" found at http://p5lyon.tumblr.com/ProcessingJSTumblrEn
