+Fetch a random pic from a random blog (of a given list).
+
+This is [scrapthumb](#scrapthumb) rewritten from scratch and better. Now the
+Tumblr API is used so you need an [api key](https://www.tumblr.com/oauth/apps).
+
+In a nutshell:
+
+```
+# scrap="$(APIKEY=Your-Api-Key fetchpic)"
+# uri="$(echo "$scrap" |cut -d'|' -f2)"
+# feh --bg-fill --no-fehbg "$uri"
+```
+
+Put this in your `.xinitrc` to change the wallapaper each 5 minutes and append
+the pic URL and blog name into `/tmp/fetchpic`.
+
+```
+while : ; do
+	scrap="$(APIKEY=Your-Api-Key fetchpic)"
+	uri="$(echo "$scrap" |cut -d' ' -f2)"
+	feh --bg-fill --no-fehbg "$uri"
+	echo "$scrap" >> /tmp/fetchpic
+	sleep 300
+done &
+```
+
+Enjoy.
