Not to take this too far off topic...
Hmm, ok it seems like there is something wrong in my electronics theory there, which wouldn't be a surprise at that time morning (3am); or at all . It looks like my reasoning that in parallel each LED would try to draw ~10ma (~14v - LED drop (3.5v) / 1000 = ~10mA) is false. If it were true and each did draw that amount then the 1000 ohm resistor would be trying to dissipate nearly 4 watts, way to much for a 1/4 watt resistor hence the frying, however a circuit simulation supports what you said Alan. I'll post the simulator later (appears to be a handy web based tool); I'm going to bed now, it's almost 04:30 and I'm making a lot of spelling mistakes as I type!

Tim, I love that you reason through the problem.
However, it appears one of your fundamental assumptions is flawed. No component "draws current" even though that is the common lingo. There is no suction, vacuum, or otherwise negative pulling force. Rather,
components "flow" what is available to them.
How's this for an analogy... a bucket full of water has a 1" hole in the bottom that drains into another bucket below. Does adding more buckets below for the water to drain into increase the rate of water leaving the upper bucket?
As the resistor (hole in top bucket) is setting the total flow, adding components (buckets below) simply divides that flow across each of the components. The total current (volume of water) doesn't change. Each lower bucket simply gets a percentage of the available water. Hence why LEDs get dimmer as you add more of them when flow control (resistor/hole) is on the supply line (blue wire/top bucket).
