This one is pretty neat and simple. Sempoi roughly means simple. You can put up a large horizontal banner as you can see in the demo page. And like the previous template I've just made, Bannr, there're flexible number of columns - either 3 or 4 columns - and you can customize each one of them easily.
If you want to upload a header image of your own, the size is 860 x 120 pixels.
Overall, i think this one is really one of the nicest one I've made, in terms of its simplicity. If you've used one of my templates before, you'll know how easy it is to change the whole thing, like the color combinations, into how you want it to look like.
