Art has four self-portraits on       | 1 | | 2 |
display in his house, each           |___| |___|
depicting him in a different          ___   ___
location.                            | 3 | | 4 |

Given the following:

1. Painting #1 is not in oils.
2. Painting #2 shows Art either hang gliding or on a motorcycle.
3. The painting of Art next to a windmill is done either in acrylics or tempera paints.
4. Art's hang gliding picture and the one done in tempera paints are in different rows.
5. The painting of Art surfing (which is not done in acrylics) is above the watercolor.

Find out what each painting depicts the medium Art used to paint each.

For simplicity I've refered to the pictures as P1,...P4 and the clues as C1,...,C5

STEP 1
C5 means that either P1 or P2 must show surfing, but C2 has P2 as either hang-gliding or motorcycling.
Therefore P1 must depict surfing. Which in turn means that P3 is a watercolour (from C5).

STEP 2
P4 must be the windmill scene - since P1 is surfing, P2 is hang-glinding or motorcycling and C3 tells us that the windmill wasn't done in watercolour (and STEP 1 told us that P3 is watercolour).

STEP 3
C1 says that P1 is not in oils, C5 says that the surfing pic (which we know is P1 from STEP 1) is not acrylic and STEP 1 told us that P3 is the watercolour - therefore P1 must be in tempera paints.

STEP 4
STEP 2 showed that P4 is the windmill and C3 says that the windmill is either acrylic or tempera. STEP 3 just showed that P1 is in tempera. Therefore P4 must be in acrylic. This also means that P2 must be in oils as it is the only medium left.

STEP 5
STEP 3 showed that P1 is in tempera and C4 says that the tempera painting and the hang-glider are in different rows, therefore either P3 or P4 must depict hang-gliding. STEP 2 showed that P4 is the windmill, therefore P3 portays hang-gliding. This also means that P2 must depict motorcycling.

So in summary we have:
P1: Surfing in tempera paints
P2: Motorcycling in oils (sounds dangerous!)
P3: Hang-gliding in watercolour
P4: Windmill in acrylics.
