Celebrate your travel triumphs by grabbing a large rock and hoist that bad boy! You’ll feel the blood rush right to your primal soul, which coincides nicely with a pump in your deltoids, core, and triceps.  Now share it with other like-minded travel savages on our Twitter page @rockhoist

It feels good, doesn’t it? It should, it’s based on a proud history of human rockhoisting. 4,500 years ago, thousands of Egyptians were lured to the exotic site of the first pyramids by a free beer tasting. After a few rounds, happy citizens were naturally compelled to hoist rocks, next thing you know…BAM! 1st wonder of the ancient world, thank you very much.

Wherever your wanderlust takes you, be sure to leave your mark. Grab hold of a rock and thrust it triumphantly skyward. Damn it feels good to be a rockhoister. Also that might be the only time in eons that noble rock got a birds-eye view of its own neighborhood. Nice work. You’re a sweaty, rockhoisting, vagabond, bohemian, genius, pirate! Pass it along, brothers and sisters! Hell, who knows what we can build with some rocks and a kindred spirit … - Get amongst it.



Last year I wrote a program which plays songs from people’s tweets. The program sat around gathering dust for some time, so I’ve decided to break it out again and have some fun with it.

Here’s how it works:

Send a tweet to @Pegleg_AU with your note names, separated with spaces. Check the webcam feed to hear your song being played out loud. The following diagram illustrates the note names (note that only one octave is currently supported*). Notes


A basic song:

@Pegleg_AU C3 E3 Gb3 E3

A song using chords:

@Pegleg_AU C3D3 Ab3Bb3 B3


We have shutdown the webcam feed, but it was fun while it lasted. Thanks to everyone who tweeted your music! 

Check back here for updates to the script.


The full source for this program is available on the github repository.

* I plan to add additional notes at some stage, however there is a bit of effort involved in converting the samples to the correct bitrate. Of course, anybody is welcome to help me add these :-) The piano samples are available from the University of Iowa Electronic Music Studios.
