Previous designs


Note: now there's a QUACK page with details on some other ideas that were never brought to fruition.

An order of these beautiful QERM t-shirts was made in April 2008 and fulfilled in May. Those who did not take part in the order and still want a t-shirt have a few options (none of which are as good or cheap as being part of the original order). And if you're James Murphy, then you better make sure you don't get crossed up in the world of flying squirrels and salmon, because who knows what might happen to you for spreading heretical ideas.

The 2008 membership of the QERM Unique Apparel Creation Kommittee (QUACK) was Derek, Dawn, Kristin and Ian. Aditya also attended some meetings, but by unanimous agreement was not allowed to become a full member. Also, Tommy, Eli, and Joel were involved at some point as well. Most of us are no longer associated with QERM on paper, just in our hearts.

QUACK is dead! Long Live QUACK!

Image files

The PNG files that were used to create the designs below are available through this wiki (see Category:Logos for a better view of selection):

  • Squirrel_salmon_black.png Squirrel salmon black.png,
  • Squirrel_salmon_white.png Squirrel salmon white.png,
  • Squirrel_salmon_black.jpg Squirrel salmon black.jpg,

You can upload these to CafePress.com or other online printers to make your own t-shirts or other stuff. For example, here's a mug ($10.99) available here. Note, the JPG included above was used in this case because the PNG file didn't show up on CafePress (but only the one image, not the others).

Green Shirt

The order tally for the green shirt with the equation on the back and the awesome squirrel-salmon logo on the front was at 37. This puts the cost per shirt at the low low price of $10.77.

Black Shirt

The black, organic cotton shirt will have a more exclusive ownership, with 20 orders. It was described by one responder as reminiscent of the "skanky bands from the late 70s/early 80s." I believe this indicates that the design was a success based on the goals set by the designers. What strange circumstances led their math addled minds to cook up these goals is a separate question. The smaller number of orders and the more expensive fabric put the cost at $14.43 per shirt.

For some reason, BlueCotton.com doesn't like to provide their formula up front: you have to enter a quantity to get a price. However, it appears from the following analysis that the relationship is pretty simple. For the grass green short-sleeve shirt shown above, the price is based on a fixed cost plus a reasonable price per shirt. However, if you go below 6 shirts, this model breaks down and you pay a lot more, so for small orders it would be better to use CafePress or other print on demand companies.

Note: Derek says that BlueCotton changes their pricing all the time, so don't treat these prices (from July 13, 2010) as gospel. The best approach is surely to add a couple bucks to any t-shirt price to buffer against rising costs, and put any profits toward beer.
