Hacky JS file hilighter - takes a URL to a JS file (in the querystring - add ?file=https://url.to/my/javascript/file.js) and renders it nicely... -ish.

	# v1.0: hacky but seemingly working
	#
	# Pop this into a toolbar button's script window in Houdini
	# Select a camera (or a camera switcher) and press the button
	#
	# A newly generated python script is now on the clipboard.

Houdini control from a Behringer X-Touch One using pygame

	# h's super dodgy, super-hacky MIDI controller for Houdini code
	#
	# Designed to get a Behringer X-Touch One controller to control Houdini
	# while feeding back current frame and status to the lights and readouts
	# on the controller. Super cool.
	#
	# But this really, really, shouldn't be public. My Python-fu is a little raw.
	# But it may give someone a useful starting point...

Blur objects at infinity depending on camera settings - After Effects expression

	//
	// This expression, applied to the blur radius of a Lens blur effect, will calc the right amount of blur
	// to apply to objects at infinity (eg star fields) depending on the focus dist / aperture of the current active camera
	//
	// For safety it maxes out at 100 px (!)
	//
	try {
	focLen = (thisComp.activeCamera.cameraOption.zoom * 102.05) / thisComp.width;
	blurDiam = (focLen * thisComp.activeCamera.cameraOption.aperture) / (thisComp.activeCamera.cameraOption.focusDistance - focLen);

Houdini to AE camera animation clipboard exporter (now with Zoom! Woo!)

	# Note: there's no error-checking in this script, but it alters nothing within the Houdini scene, so it'll just
	# fail with an error if you try running it without a camera selected. No harm done.

First attempt at getting AE camera data into Houdini (hacky woo)

	# Ultra quick'n'hacky AE camera animation importer for Houdini.
	# Create a new shelf, create a new tool, paste this into the script box.
	#
	# In AE, select the Orientation and/or Position keyframes, and Ctrl/Cmd-C them to the clipboard
	# Open a new text file (Notepad or Textedit) and paste the clipboard contents in. There's your keyframes.
	# Save the text file somewhere and amend the filename line below to suit
	# In Houdini, create a camera (it's up to you to set the same zoom / aperture as the AE one).
	# ... and run this script (well, press the shelf button you stuck this on)
