Sorry this review is late. I had a few things I wanted to say about Friday's strip, but no desire to actually put them into complete, well thought out paragraphs. If you want that, you'll have to wait for the guest review of 965, which I'll post this afternoon or evening.
Title: Dorm Poster; alt-text: I was going to record an album with that cover under the name "PINK FTFY", so it'd come after them on the store CD rack. But at this point music stores are just rooms where CDs are set out to age before they're thrown away, so probably nobody would see it.
Okay, first of all, you don't need a convex lens for the rainbow light to refract back into white light with a second prism. Newton didn't use one. Yes, it wouldn't converge as the image shows without the lens, but if you want to delve into minutia, the light lengths are uneven (between the lens and the prisms) and it should be diffracting inside of the prism, not outside. Guess you didn't really "fix that for you," did you Randall.
And while we're referencing the alt-text, get off your frigging elitist high horse, Randall. More people go to record stores than read your stupid webcomic. Just because you and your fanbase all use iTunes or torrents or whatever else doesn't mean that the rest of the world does. I have friends and family with shelves full of CDs. I own a binder full of them myself. Yes, they're not doing as well these days (naturally), but people still do visit them. Sheesh.
Finally, it's nice to see Randall's as timely as ever with his "moving into college dorms" comic. Guess when people started college, Randall? NOT LAST WEEK. And does it seem odd to anyone else that neither person says a word to the other? Yes, the comic is better for it, but it just feels...weird. Maybe Randall should have thought the setting through a little more before writing a comic with it.
P.S. I'm told there was a pointless stealth edit to add glasses and a goatee to the roommate. I don't have a source for this besides the forums, but come up, Randall. Really? Why?
P.P.S There are two oddities that bear mentioning in passing. First the guy's backpack gains a ridiculous level of detail between panels 1 and 6. Second, who the heck carries a poster unrolled?
