OK, so maybe this isn’t the best LEGO technique of all time, but it’s surely one of the most tedious. The effect Andreas Lenander created by stacking a few hundred transparent blue bar 4Ls (AKA lightsaber blades) to create the shimmering portal is magnificent. The shadowy figure completes the effect, while the mottled brickwork gives the whole portal an eery, otherworldly feel. Now who wants to create a Stargate using this method?
